A couple days ago, I wrote a fanpost about tackle prospects in the upcoming draft.
I'm back at it today with a review of some great guard prospects who you probably aren't familiar with. Without further ado:

Larry Warford, Kentucky

This is the kind of guy you could trade down for. AKA Mr. Dependable, Larry didn't give up a single sack this year playing against SEC defenses. At 6'3" and 343lbs, he's pretty much impossible to drive back at the QB, which is a problem certain linemen have had lately in Dallas(sorry Dr-P).
Why we should take him: He's big and strong, he's what we need in Dallas. His strength is pass protection, and I'm okay with that. With mini-man-Costa possibly playing center, there is upside in having a brick wall playing next to him. Looks like he'll go in the second round.

Alvin Bailey, Arkansas

Probably a first round talent, but Alvin has elected to foregoe his senior year and declare for the draft and, as a result, it looks like he'll slip to rounds 2-3. He's a solid 6'5" and 315lbs.
Why we should take him: He's generally been a starter at right guard, but Arkansas switches linemen around, so he has experience at left guard too. He's quick and can get to the second level. He is capable of controlling defenders with strength alone, and could become a high-level NFL guard if he is coached up on his footwork.

Possible Steal: Lane Taylor, Oklahoma State

Lane could go in the seventh round or possibly remain undrafted, but is a much better prospect than last years free agent heart-throb, Leary. He stands at 6'2" and an impressive 328 lbs.
Why we should take him: This guy is not a risky prospect. By all measures, he should outperform his draft position and, therefore, his contract. He's earned All-Conference honors and has already spent a lot of time in the weight room. Did not give up a single sack over the course of 850 snaps during the 2012 season.

Again, I've attempted to look at guys who aren't obvious, and who could potentially be of great value to the team. What say you?
