dallas thomas did a decent enough job for the vols last season, but hes nowhere near ready to handle starting lt in the nfl. He began as a guard and got moved to left tackle through injuries, but played solid all over the line. He played for a team in turmoil with a coach on his way out. Maybe some good coaching will help. he should provide good depth and possible start at guard. The critics say he lacks the foot speed to be a lt.
