49ers-Vikings: How will you track the offensive line?
One of the big issues for the 49ers last season, as we all know, was the offensive line. The team made huge additions (literally and figuratively) through the drafting of Mike Iupati and Anthony Davis. Naturally these are guys we'll be paying attention to over the course of the preseason and into the season.
At the same time, there are a whole host of bodies along the offensive line that require extra attention. There has been a bit of turmoil because of injuries, but we've also seen younger guys that could potentially emerge as key reserves. The best example of that is Alex Boone. While he has yet to impact the roster, Boone has become a fan favorite and has appeared to step up his game this past offseason. Maiocco did a player-by-player recap of last week's preseason game against the Colts and had this to say about Boone:
Entered at beginning of second half at left tackle and played the rest of the way, 31 snaps. He was called for a holding penalty, but his feet looked much better than last summer. He did a very good job in the second half of handling defensive end Ervin Baldwin one-on-one.
Boone will likely get a fair amount of playing time this Sunday against the Vikings and I had a query for folks. When I was going through the game threads checking out comments, there was some discussion about the footwork of the players. While I have a good knowledge of football, my analytical abilities when it comes to offensive linemen can be a bit weak.
Given that, I have a question for everybody. When you're watching the preseason games, or any game for that matter, how do you follow the play of the offensive linemen? Given the camera angles and how quick play is, are you utilizing some kind of DVR and rewinding throughout the game? Or do you focus on the o-line as much as you can from the camera angles and go with that first hand look?

He only whiffed once, the got much better
by ericalancanty on Aug 20, 2010 12:56 PM PDT up reply actions
So long as he minimizes the whiffs
He will exceed my expectations for him from the draft. He did better than I expected for his first game and was only the 2nd weakest link of the starters.
CHILLLLLOOOOOOO!!!!
Gimme 1 round!

Chilo was not weaker than Davis
I just barely finished re-watching the game.
Rachal whiffed badly on one pass play that caused a sack but bailed out Davis at least once.
Davis is susceptible to speed moves whether inside or outside. He’s got to develop better footwork to handle that but he performed better than Snyder would’ve and he’s a much better run blocker than Snyder ever was.
Logic merely enables one to be wrong with authority
Very possible I didn't notice Chilo bailing out a Davis mental mistake
I’d have to watch it all on tape for that and I don’t have it DVR’d

I really only notice a lineman’s poor footwork when defenders are noticably beating him. When the OL is doing its job, I’m not paying much attention to it, because it’s easy notice a huge pancake block regardless. The same can be said about a missed block, I can’t help but notice the poor play because it’s so obvious. When it’s replayed I then see just how poor the footwork was, or if the player needed better extension, etc. I like it better when the OL is doing its job, and I don’t have to care.
No crow for me thanks, Brandon Jones cut.

unless I re-watch, I only pay attention to them if they’re getting beat, or just got beat and there is a replay

Ah ha! The key topic of the weekend
I’ve tried not to read much into the offensive/defensive line performances against the Colts, frankly outside the defensive ends the Colts interior sucks. Every team in the league can push them around.
The Vikings are a true measuring stick, elite units on both lines. Defensively if the 49ers can get the upper hand against the run and pass rush it will verify their presumed elite status. Offensively the 49ers need to stay competitive inside the trenches, they will lose some battles. If they make plays against the Vikings front seven they can make plays against any team in the league, meaning the talent is there just need time to develop the consistency.
I can't wait for Iupati to pancake one of the Williams sisters

Angles wrong
Now enough cameras or angles used to detail each lineman. Exceptions, of course. Too often you’d see lack of coordination. Ex: Bass gives half-hearted attempt to double NT & leaves a huge gap to his left which is easily exploited by LB for sack.
watch their feet at 3 intervals
First step off the line: a lineman’s most important move. Essentially, hit first or be hit. Movement at the point of contact: first step wont matter if you don’t move your feet after contact. This is what made Davis look so bad on his whiff. Came off the line and…stopped. dude ran right by him. Finally, foot movement after contact is sustained: this is what creates the wonderful “pancake” block. Get under those pads and drive. Essential in pass blocking as well. Since you’re not really driving off the line during a pass play, you must be light on your feet to stay in front of your man. On top of all this, STAY LOW! Im astonished at how many NFL linemen forget simple fundamentals. Anyway, this is what im looking for when I study an olineman on a play.
Much easier, all-mighty Megatron, then attacking the real threat...The Autobots moonbase!!

RATING THE 49er O-LINE?
I dont pay as much attention to the o-line as much as the rest of the offense, but i usually rate it by 1. # of QB saks, 2. # of holes for frank G. 3. Time QB has to throw passes. If all these are good, then the o-line is good, if anyone of the above take place,
then i look to where or whom its coming from. anyway, thats how i rate the o-line during games. GO NINERS!!!!
I have to re-watch to really evaluate them
Pass blocking: then you watch to see are they in control or are they frantically reactiing to the defensive player? If they are reacting, are they doing a good job of countering and recovering or just making a last-ditch effort to thwart a sack? You want to see them letting the rush come to them, then channeling it where it needs to go, or just plain stopping it. Against superior competition (Jared Allen, for instance) you want to see they can roll with it and at least minimize his impact, push him out and around, slow him down at least, etc. Sometimes though the team just has to double a guy or send a back to chip him.
Run Blocking: Do they latch on inside where holding wont be called and stay with the defender if it’s an iso play? Do they push the defender away from the hole or pancake him? If the play calls for it can they get a really good shot on the first level before releasing and seeking out the second defender? Are they doing a good enough job on the first guy to keep him from thwarting the gain? Are they finding the second level and driving them?

As far as the roster battle at O-Line goes
I did a fanpost on that because it was really getting to me and lots of disagreement going around on that topic.

Boone
Not a fan-favorite here. I don’t get why everyone is high on him.
Um, how am i supposed to sign this thing? It's a computer?!
Because he's massive
and he has talent. He was just always in horrible shape cause he was a binge drunk.

by ItBurnzWhenIP on Aug 20, 2010 10:17 PM PDT up reply actions
How do you know he has talent?
This is what I don’t get. He lost 15 lbs and broke a sled in drills but he hasn’t actually done much of anything.
You can’t beat up on Nate Davis fans if you’re a Boone fan because Boone has even fewer reps
Logic merely enables one to be wrong with authority
He came out of Ohio State and was just a wasteful drunk for his college career… he HAS to have talent to succeed in that program. Not to mention he’s 6’8" 320 out of shape.
Here’s another way I know he has talent. He was a 5 star 6.1 graded recruit coming out of HS.
Here’s his scouting report from that
One of the most touted players in the nation at Lakewood St. Edward, Boone was the No. 3 offensive tackle prospect by Rivals.com and the 20th-ranked player overall. Was praised for having great footwork despite standing 6-8, 315 pounds and has a frame that could carry even more muscle. Totaled 50 knockdowns as a senior. Started at right tackle in the U.S. Army All-American Bowl last January, but might be better suited for the left side. Played for John Gibbons.

Here's the difference between me bashing Nate and this
My problem with Nate is his competency with the playbook. If we were guaranteed to have the same system for 10 years Nate would be great but that isn’t the way the NFL works. To be a successful starting QB in the league you gotta be able to pick up a playbook and learn the damn thing to at least functionality in 1 offseason.
Now here’s the other thing. I’m not calling for Boone to start over Staley based on him having 1 solid game against backups even if he did play well.
Just remember Boone was a 5 star recruit while he was a drunken party kid. If he stays on the straight and narrow that is a HELL of a lot of talent and size to have focused on a goal.

For comparison
Anthony Davis is a 6.0 and all anybody ever talks about with him is ZOMG HIS UPSIDE IS SO INCREDIBLE!!! Well Boone’s was once upon a time considered higher.

College prospect analysis is all it is. Nate is being brought along slowly.
Boone is gonna play where? He won’t be a starter before Davis, without injury. Nate Davis was brought along slowly, and questions were asked about him handling the playbook and Sing and Raye defer questions and don’t provide muh info, it doesn’t mean he couldn’t pick it up quickly if he had too. Vince Young appears to be a slow learner as well, and that for damn sure isn’t the last QB or only that learns slower than a P Manning. Davis was a 1st round prospect until the dislexia info came out. Its easier to be a first round OL prospect than a 1st round QB prospect. Davis could easily be our QBOTF.
Black Sand Ninja!!!
Davis was never a first round prospect
not playing in the conference he played in
Logic merely enables one to be wrong with authority
Fans liked to say he was
but in reality no he wasn’t. Especially not after he personally lost the 2 most important games of the season when he finally played halfway decent teams. Look up his stat lines against Buffalo and Tulsa.

Nice piece of research
I had never seen Alex Boone’s Rivals.com ratings and scouting report before. About in line with the Ohio State U. hype, or even better. Thanks.
For the more cerebral among us, another way to evaluate OL play is based upon the way nuclear physicists look for new subatomic particles. You look not for the particle itself, but for its influence on what happens near it. If all of the pass rush is coming from the right side, Iupati and Staley (or Boone) are doing their jobs. If the RB is getting 5-6 yards per play over the left side, Iupati and Staley (or Boone) are doing their jobs. Or vice-versa. Same metric for the right side, but it is Rachal and Davis on the evaluation scale. If there is all the time in the world for Smith to throw, everyone is doing their job. You don’t need a DVR at this level of evaluation. Center is harder to “see” this way, especially against a 3-4 defense where the center often is asked to be half of a double team. But look for down field blocking against a LB on a running play that works, and you may see Heitman or Baas in the mix, and that means they are doing their job.

I don't expect Boone to start the beginning of a season anytime soon.
But the guy has the best natural ability of any of our backups. I think he could be our 3rd OT sooner rather than later and is a fantastic insurance policy and leverage against Davis if he decides that he wants more than he is worth when its renegotiation time.

It's tough...
I find myself having to rewind it to see how the guy got beat or whatever. From what I saw Davis did not look too impressive, but Iupati looked strong. I expect them to develop and thrive as unit in the reg season. It’s tough to judge in preseason though.
One thing to keep in mind is that Iupati has Staley on the outside. Davis is outside of Rachal
Given that, Iupati will have it easier than Davis.
EIther way last week was the first game for either in the NFL against real players. It takes a little while to adjust to everything. They will have good and bad plays on and off throughout the first half of the season. I think they should be doing great after that.
"Whether you think you can, or you think you can't, either way, YOU'RE RIGHT !"
Also
Remember against the Colts, Davis was facing one of the best in the league while Iupati was generally matched against pushovers.
and second level defenders like LB's
Vernon Davis, Michael Crabtree, Tedd Ginn/Delanie Walker, Frank Gore, Brian Westbrook...which one is getting the ball and where?

But this weekend...
I can’t wait to see how the rooks hold up against the Viking’s front line. I’m expecting a couple sacks early on, but I would be pleasantly surprised if we provided good pass pro.
Jared Allen will take Davis to school..
…albeit for a couple of series, I’d expect. Anyway, Davis needs all the off-season schooling he can get.
won't it be Joe Staley going up against Jared Allen?
When life gives you fruit, add a bunch of sugar to it.
Their RE is just as deadly, Allen doesn't rotate much.
Both of our Tackles will be tested.

Staley shut down Allen last year
Probably the best game of Joe’s career.

who made the play?
Just because gore is sprinting down the field for a big gain, doesn’t mean he got there by himself, Did Bass come around the corner and level the linebacker? Did Chilo and Eric blow up the nose and push him down the line for a huge hole? I like to see who made the play Same on the D-line, just cuz spikes just dropped steve jackson w/ a prefect ear hole shot, i mean what happened? did Sope take on a double, or did Manny string the play out down the line, Man I’m ready for football
When watching it live
I watch for pleasure and do very little analysis other than quick opinions and impressions.
I always go back and re-watch a game—generally a couple of times to focus on specific issues/players.
Logic merely enables one to be wrong with authority
on pass plays
you can watch the o-line until you see the QB throw the ball out of the corner of your eye.
then you can follow the ball, because it doesnt really matter what the o-line does after that.
When life gives you fruit, add a bunch of sugar to it.
Watching and then analyzing 49ers games ...
I record every 49ers game on DVR.
During the pre-season my biggest interest is player development and assessing rookies. Thus, when watching pre-season games I watch in real time just for pleasure but also make notes of those plays and/or players that I want to rewatch later.
From my notes I go back and rewatch different portions of the pre-season games — focusing of noted plays or players (particularly rookies and competitors for key cuts) — several times, a lot in slow motion.
During the regular season my rewatching focuses on key plays during the game and reasons (key players) involved in the success or failure of the play.

Interesting post
I like to think I’m average when it comes to actual football knowledge, and unfortunately for me, analyzing the play of the O-line is a weak point of mine. Much of my analysis comes from the support of in-game replays, sportscenter/nfl.com highlights, and the 49ers beatwriters. I don’t have the benefit of that DVR thingy. Usually, though, when I’m not relying on these other forms of “support”, my vision of the O-line’s play is “peripheral” in relation to the QB. At best, I’m able to tell who’s being effective at containing the rush (on an individual basis) by looking at the frequency at which the QB is being pressured from all directions, and that is, straight ahead, to the right, or to the left. For instance, if Shaun Hill is constantly being rushed by the Saints Will Smith throughout the entire game, than it’s safe to say that Barry Sims is the one responsible for the breakdown in protection. In this case, I really do end up simplifying things, but I think it works out well for my evaluation of the O-line from an individual standpoint. That’s pretty obvious, right? If a consistent rush is coming from one direction, you can usually identify the weak link.
As far as the team effort is concerned, here, it’s hard for me to evaluate the o-line. My reason? I think much of the success of the protection has as much to do with the QB’s abilities as it does with the individual players on the o-line (hope that made sense). In other words, is the QB able to “use” his offensive linemen by moving around in the pocket (classic example: edge rushers attack from the outside, so as the QB, you need to have the presence of mind to slide up in the pocket to “buy more time”)? Also, is the QB decisive in his throws and does he get rid of the ball quickly? Just my opinion, but I recall the 49ers o-line being very bad during Jeff Garcia’s tenure, and yet, there were times when I thoughht the o-line looked pro-bowl"ish" because of Garcia’s stellar play. You can certainly make the argument that the o-line simply sucks if the QB has to 1) “use” his o-line in that manner, and 2) get rid of the ball that quickly, but that wouldn’t be fair. What the heck is my point here? I suppose my point is that, at least from a team effort perspective, I evaluate the o-line’s play based partly on the play of the QB. I say the O-line is doing a good job if he has sufficient time to get off a throw to both his check down receiver, and a streaking Vernon Davis who reaches 20-25 yards down field (at the point of the throw). If this amount of time is not afforded (3-4 seconds), then I’ll say that they did poorly. (I’d like to keep going on the QB, but I’m afraid I’m losing some folks here and not making much sense.)
The running game, like the passing game and the QB, has a lot to do with the play of the RB as well. How fast does he hit the whole, and/or how patient is he in waiting for the hole to open up? Remember Kevan Barlow? it was said that the o-line sucked when he was the starter. In comes Frank Gore, and all of a sudden, the o-line improves. Strange… Anyway, runs to the edges are pretty simple for me to analyze since the live camera angle shifts, allowing you to see everything unfold. It’ll be pretty obvious, say, if a guy like Kwame Harris completely misses a block, and allows the outside linebacker to crush Frank. Runs up the gap are a bit more difficult, but the replays usually help me track the line’s play.
Wow that was long. Sorry…
