Idk why people are so high on him. I'd say its an Alabama thing, but with guys like Fluker, Andre Smith, and Chance Warmack being the banner carriers, I don't think it's that. He isn't a terrible run blocker, but I wouldn't trust him enough in pass sets to leave him at tackle if I could avoid it. I think Ramczyk and Bolles should go ahead of him and a couple of the guards should too.
I'm 99% sure Wagner walks so they'll definitely need to replace him. The FA RT class isn't actually that bad behind Wagner. If we could get a cheap guy like Vollmer, Menelik Watson, or an even lower guy like Jordan Mills to compete with Lewis, I think they'd be in good shape.
