Offensive linemen at a glance

T Greg Robinson*Auburn6-53324.921

A third-year sophomore who started 25 games the past two seasons; a bit raw but displayed freakish athleticism at the Combine and has franchise tackle potential.

T Taylor LewanMichigan6-73094.871

Explosive athlete, dominated Big Ten competition in 48 games over four seasons, and dominated Combine in February. Zone blocking teams may prefer Lewan over Robinson.

T Jake MatthewsTexas A&M6-53085.071

Could be first tackle off the board. The Son of Hall of Fame center Bruce Matthews is an NFL-ready left tackle for zone blocking teams, but needs to improve run blocking.

T Morgan MosesVirginia6-63145.351

Three-year starter comes from good line of Virginia tackles, including D’Brickashaw Ferguson and Branden Albert; Moses’s best fit may be at right tackle in the NFL.

T Zack MartinNotre Dame6-43085.051

Started a school-record 52 games, but doesn’t have ideal length for left tackle; excellent athleticism and ability to pull and trap; best fit might be as a guard and swing tackle.

C Weston RichburgColorado State6-32985.191-2

Solidified spot as top interior offensive lineman in draft with a strong showing at Senior Bowl; can play guard as well.

G Xavier Su’a-Filo*UCLA6-43075.041-2

Athletic, polished blocker in run and pass game; top guard in a year without elite talent; sat out two years for a Mormon mission but started all 27 games the past two seasons.

T Ja’Wuan JamesTennessee6-63115.342

Shows good athleticism for his size; started 49 games in four seasons with the Vols; held Jadeveon Clowney without a sack in 2013 matchup.

T Cyrus Kouandijo*Alabama6-73225.592
Has makeup and size to be a dominant left tackle, with a couple of warning signs; was inconsistent his senior year and generated concern about his surgically repaired knee after a poor Combine showing.

Best of the rest: T Antonio Richardson, Tennessee (6-6; 336 pounds; 5.30; 2-3); G/T Cyril Richardson, Baylor (6-5; 329; 5.36; 2-3); G/T David Yankey, Stanford (6-6; 315; 5.48; 2-3); C Travis Swanson, Arkansas (6-5; 312; 5.26; 2-3); C Marcus Martin, USC (6-3; 320; 5.09; 2-3); T Jack Mewhort, Ohio State (6-6; 309; 5.37; 3-4); G Brandon Thomas, Clemson (6-3; 317; 5.09; 3-4); G Gabe Jackson, Mississippi State (6-3; 336; 5.51; 3-4); T Cameron Fleming, Stanford (6-5; 323; 5.28; 3-4); C Bryan Stork, Florida State (6-4; 315; 5.18; 4-5).
