1. Alex Barron, Florida State Positives: Ultra-large frame athleticism, footwork, body control, quick-set ability, knee bend, long arms His exceptional pass-protection skills and ability to line up in the prime left-tackle spot should make him the first offensive tackle off the board, probably in the middle of the first round. Negatives: Upper-body strength, aggressiveness, overall technique, choice of run-blocking angles. 2. Jammal Brown, Oklahoma Positives: Upper-body strength, balance, athleticism, body control, footwork, quick-set ability, long arms He has enough talent, particularly in pass protection, to likely warrant a low first-round pick. Negatives: Aggressiveness, run-blocking technique, injury history. 3. Khalif Barnes, Washington Positives: Athleticism, speed, footwork, body control, balance, quick-set ability, choice of run-blocking angles, overall technique A strong performance at the National Scouting Combine figures to have solidified his position as an early second-round choice and perhaps even a low first-rounder. Negatives: Consistently high effort, lower-body strength, hand placement. 4. Marcus Johnson, Mississippi Positives: Size long arms, hand placement, body control, balance, toughness, choice of run-blocking angles, quick-set ability Although he was a guard for most of his college career, his size makes him a likely tackle in the NFL and a probable early second-rounder. 5. Adam Terry, Syracuse Positives: Size long arms, quick-set ability, techniques, athleticism, body control His outstanding senior season should make him a solid second-round selection. Negatives: Lower-body strength, ability to handle bull-rushers.
