Taylor Lewan is considered the third-best offensive lineman in this class (Dane Brugler, Rob Rang and Derek Stephens, NFLDraftScout.com via CBSSports.com). He stands 6'7" and weighs 315 pounds.
Lewan made 28 consecutive starts at left tackle for Michigan and was the 2012 Rimington-Pace Award winner (Top OL in the Big Ten). He is a former AP and Walter Camp first-team All-American and has drawn comparisons to former Dolphin Jake Long.
His physique and skill set makes him NFL ready, but there are some questions about his maturity. He was interviewed by police on November 30 for his alleged involvement in the assault of an Ohio State fan (Mark Snyder, USA Today). Lewan denied any involvement, and no charges were brought against him.
Ordinarily, I would say it is unfair to label a person over what appears to be an isolated incident. However, the Dolphins may have greater concerns over the assault allegation than most teams after the Martin-Incognito saga.
Lewan will certainly be asked about that incident during his interviews with NFL team reps. How he explains and handles himself during the interview process could be a deciding factor for Miami. After all, his on-field work speaks for itself.
