In 2011, the 49ers had two players rotating at the right guard position: Adam Snyder and Chilo Rachal. Neither of which will be on the San Francisco roster this coming season. The organization had been linked to a couple offensive linemen in former Carolina Panther Geoff Schwartz and former Pro Bowler Leonard Davis who missed last season.

Nothing further has developed as those two appeared to have come and gone, and San Francisco is knee deep in the Peyton Manning sweepstakes without solidification amongst the offensive line.

The 49ers will no doubt correct the position, but it seems they do have faith in their draft pick from last year, Daniel Kilgore to compete at the spot. With free agency ongoing and Manning busy making his decision, I suppose news can break at any moment that they've brought in a veteran, but nothing's indicated that will happen.

At this point, it's starting to get the feel that the 49ers will invest a high draft pick in an offensive lineman next month. Now, I suppose the dream scenario would be Stanford standout David DeCastro dropping closer to the back end of the first due to a draft class overpopulated with talent.

Personally, I think a more realistic player the 49ers could land is Cordy Glenn, an offensive lineman from Georgia. Glenn is a projected first rounder, and I wouldn't be shocked to see him fall to the Niners late. Glenn is a terrific physical specimen, worthy of his first round status -- if he's within reach, San Francisco should snag him.

DeCastro and Glenn may be too high for the 49ers, but with a hole as glaring as the one they have, trading up wouldn't be unreasonable. Wisconsin C Peter Konz, Ohio State OT Mike Adams and Stanford OT Jonathan Martin are three other top-rated offensive linemen, that if San Francisco's lucky, will fall to the back of the first round.

I expect these guys to maybe get taken between 14-28 range. But it doesn't end there with the offensive line guys; the second tier guys are looking sharp this year as well. Brandon Brooks from Miami (OH) and Amini Silatolu from Midwestern State are guys that could be gotten after the first round.

But someone like Kelechi Osemele from Iowa State could prove to be a great interior offensive lineman at the next level. He is someone that could fall in the 49ers lap come draft day, and depending on how they value him, he could be taken.

There are plenty of offensive weapons to be had in the later rounds, and everything on the offense starts in the trenches, therefor it is the most important. Also, since Mario Manningham reportedly agreed to a two-year contract with the 49ers, this makes them less likely to take a wide receiver in the first round. In fact, it tips the scale toward selecting an offensive lineman.

Report: Geoff Schwartz expected to visit the 49ers Tuesday, after visiting with the Minnesota Vikings on Monday.
