49ers-Eagles film: Looking at offensive line’s sacks allowed in wake of Jimmy Garoppolo trade

The 49ers have a terrible offensive line. We take a look at what Jimmy Garoppolo could be in for based on 5 sacks allowed vs. the Eagles.

NFL: San Francisco 49ers at Philadelphia Eagles Eric Hartline-USA TODAY Sports

The San Francisco 49ers looked bad against the Philadelphia Eagles in a number of ways. C.J. Beathard looked bad throwing the football. The offensive line looked bad blocking. The defensive front looked good at times, but bad at others. Overall, it was a poor showing.

But the offensive line played worse than any of them, and that likely can be attributed to the loss of Trent Brown — their best lineman this season, who missed the game with a concussion — and Joe Staley, who left the game with an injury due to what I took to be a very illegal hit by Fletcher Cox, though not one we can ascribe malicious intent to.

That’s their starting tackles out, which means Zane Beadles got playing time, and it did not go well. Garry Gilliam, the primary swing tackle, also went down, which forced Erik Magnuson onto the field for the first time.

The 49ers just acquired Jimmy Garoppolo in a trade with the New England Patriots. I think he’ll do just fine in San Francisco, a lot better than Beathard or Brian Hoyer. But I hope he’s not faint of heart, because watching these gifs has me worried for his safety, especially if he plays right away.

Let’s take a look at the sacks allowed.

5:31 of 2nd Quarter, 3rd and 6 from SF 29: Beathard sacked at SF 21 for -8 yards (Fletcher Cox)

It’s easy to see what went wrong along the offensive line on this play — Daniel Kilgore was beaten handily by Fletcher Cox. It looks like the running back maybe is supposed to chip, but at the end of the day, the blame can be placed squarely on Kilgore.

Here’s what Beathard could see down the field: basically nothing. He might think he has a deep, deep touchdown over the top but that’s a tall ask. None of the routes developed quickly enough for Beathard to get the ball out before he’s being dragged to the ground.

1:51 of 2nd Quarter, 1st and 10 from SF 25: Beathard sacked at SF 19 for -6 yards (Brandon Graham)

Hey folks, remember Zane Beadles? Here he is not even coming close to preventing Brandon Graham from slamming Beathard into the ground. Beadles might not even get his hands on Graham properly before the play is blown. Brandon Fusco is there to assist Kilgore in the center, and doesn’t have the quickness to get back and cover for Beadles’ mistake. Beathard has barely finished his dropback by the time he has guys in his face.

This is a first down, so a gain short of the first down marker is acceptable. Unfortunately, Beathard isn’t really given time to get the ball away to his two underneath options, both of whom are open for a gain of around 5 yards. Just as his men are turning, he’s stepping up to throw and getting hit by Graham.

0:17 of 2nd Quarter, 1st and 10 from SF 49: Beathard sacked at SF 49 for 0 yards (Mychal Kendricks)

That’s Erik Magnuson lined up at right tackle ... and that’s Erik Magnuson getting beaten at right tackle. Beadles barely contains his guy on the left side, but ultimately, it’s Magnuson who can’t handle his man, forcing Beathard to move. But Beathard ... doesn’t move particularly well.

I don’t know if Beathard was stretching things out in hopes of throwing a pass, but he has one underneath option on either side of him — and it’s a first down play — so I don’t know why he didn’t get rid of the ball. He had to see there was no running lane and he had to see that none of his deep options were going to pan out.

6:39 of 4th Quarter, 1st and 10 from PHI 38: Beathard sacked at 50 for -12 yards (Graham) PENALTY, roughing the passer, no play

This one is on Magnuson, officially, because his man gets to Beathard first, but Beadles also does a terrible job at getting his guy. It’s obviously supposed to be a deep drop and the 49ers are ill-prepared for it. Beadles even had help with a chip from Trent Taylor. Either way, there’s a penalty so we’re not going to look at the coaches film on this one.

6:12 of 4th Quarter, 2nd and 10 from PHI 23: Beathard sacked at PHI 32 for -9 yards (Vinny Curry)

Beadles, once again, is handily beaten by his man and it’s really not close. Laken Tomlinson is guarding against the delayed blitz and he can’t adjust in time to cover up Beadles’ mistake. Beathard doesn’t have anywhere to go and takes a brutal shot. Kilgore and Fusco handled their business fine on the play.

Beathard gets a guy open in the seam, but by then he’s already looking to his left, and seems like he’s going to go to the underneath outside man to be safe and get closer to the first down, but he turns right into a man flying into his stomach, so there’s little he can do.
