Tier 1
David DeCastro: Stanford (6-5, 310)
The best offensive line prospect I've evaluated since Maurkice Pouncey in 2010. He showcases the ability to get a push in-line and is a dominant move player as well. He's fluid/natural in pass protection and with a little more power in his base he's got the skill set to become on of the leagues best guards early in his NFL career.
Tier 2
Cordy Glenn: Georgia (6-5, 348)
Has had some struggles in space as a tackle prospect, but in tighter areas where he can get his hands on linemen quickly as a guard he showcases the ability to dominate. Looks like a starting caliber OG early in his NFL career.
Tier 3
Amini Silatolu: Midwestern State (6-3, 324)
He has some technique flaws that needs to be fixed and will need to kick inside at the next level. However, he's a wide-bodied athlete with a powerful/explosive frame, good foot quickness and can really pull from the backside. Might need some time, but is one of the top guards in the class with as much upside as any.
Brandon Brooks: Miami (Ohio) (6-5, 343)
Is a big, strong kid who has some lateral quickness for his size but needs some technique work. Nevertheless, has some upside and can win consistently in the run game and pass game and looks like an NFL starter in an angle scheme to me.
Kevin Zeitler: Wisconsin (6-4, 315)
A tough, strong in-line guy who you can run behind and also has some coordination on the move. Not as effective in the pass game, but can mature into an average NFL pass blocker if he learns to get off the ball more consistently. Looks like a gritty type starter early on in his NFL career to me.
Tier 4
Kelechi Osemele: Iowa State (6-6, 347)
A big, thick kid with natural strength, athleticism and flexibility. Has improved his technique and overall range off the edge, but is better suited to play inside or on the right side at the next level.
Brandon Washington: Miami (6-4, 320)
The talent is there for this guy to mature into a guard you can win with consistently inside at the next level. He needs to improve his pad level in the in-line game and tighten up his footwork in all areas. However, with a year of seasoning he certainly should mature into an above-average guard in the NFL with the talent to start at right
Jeff Allen: Illinois (6-5, 315)
He's not an overpowering run blocker, but can bend, gain leverage and seal inside. He's smooth and coordinated in pass protection, can keep his base down and warrants a higher grade because of it. Needs to play inside at the next level, but looks like a guy who can start in the league.
Lucas Nix: Pittsburgh (6-6, 310)
A good athlete for the position who can win in the pass game and seal lanes inside as a run blocker as well. Has some upside as a power play moving lineman off the ball and looks like a capable starter in the NFL.
Tier 5
Tony Bergstrom: Utah (6-6, 315)
A big, strong tackle/guard prospect with some short area quickness for his size. But struggles with flexibility in pass protection and looks limited in what he can offer an NFL offense. However, looks more coordinated and plays lower as a guard and looks like that is where his future lies in the NFL.
Senio Kelemete: Washington (6-4, 301)
A gifted athlete with a strong base, strong hands and a passion for the game. Needs to clean up his footwork and his body type makes me think he's more of a guard only prospect.
Derek Dennis: Temple (6-5, 328)
Is worth a mid round pick because he moves so well for a 325-pound lineman. Needs to learn to play lower though if he ever hopes to be anything more than a reserve. However, his fluidity on the move says he has a chance to mature into a starter.
