1. Luke Joeckel, Texas A&M
Particulars: 6-6/310, Jr.; Arlington (Texas) High
Buzz: He has been the starter at left tackle for the Aggies since he stepped on campus in January 2010. He earned some freshman All-America mention in 2010, then was a first-team All-Big 12 selection last season. Joeckel is seen as a sure first-round pick in the 2013 NFL draft, should he leave school a year early. His twin, Matt, is a 6-4, 234-pound backup quarterback for A&M.
2. Taylor Lewan, Michigan
Particulars: 6-8/302, Jr.; Scottsdale (Ariz.) Chaparral
Buzz: Lewan redshirted as a true freshman in 2009, then moved into the starting lineup as a redshirt freshman. He was a second-team All-Big Ten selection last season and looks to be the next great Wolverines lineman. He didn't play offensive tackle until he was a senior in high school; before that, he had been a defensive end. Lewan is an aggressive, physical lineman and plays with a mean streak.
3. D.J. Fluker, Alabama
Particulars: 6-6/335, Jr.; Foley (Ala.) High
Buzz: The massive Fluker, who weighed upward of 350 as a high school senior, is heading into his third season as the Tide's starting right tackle. Befitting someone his size, he is an absolute road-grader when blocking for the run, and his pass blocking has improved. Fluker was a five-star prospect who was the No. 3 recruit nationally in the 2009 signing class.
4. Chris Faulk, LSU
Particulars: 6-6/325, Jr.; Slidell (La.) Northshore
Buzz: He became a fulltime starter last season and performed admirably at left tackle. He had started the final two games of the 2010 season at right tackle. For a big guy, he is light on his feet, yet he also has excellent strength as a run-blocker. Faulk played every offensive snap in five games last season. He and Alex Hurst are the second-best tackle combination in the nation.
5. Jake Matthews, Texas A&M
Particulars: 6-5/305, Jr.; Missouri City (Texas) Elkins
Buzz: Matthews, who hasn't redshirted, is heading into his third season as a starter. His proficiency shouldn't be a surprise, as his dad, Bruce, is an NFL Hall of Famer who had a 19-year career as an offensive lineman; he also is the cousin of NFL LBs Clay and Casey Matthews. Luke Matthews has excellent footwork and is equally at home blocking for the run and for the pass. He and Luke Joeckel, No. 1 on this list, form the best tackle duo in the nation.
