Everyone knows he was much malignedb and really struggled. He often seemed lost and was one of the big reasons for the offensive struggles. But he didn't quit. He didn't transfer and with TJ Woods he has become arguably the best lineman on the team. I believe that week in and week out he's one of the highest graded lineman on PFF and now has a good shot at being drafted.
A-Rod talked about him in the media availability on Wednesday if you're interested.
I think it's pretty evident that the massive improvement along the o line and from Caleb's position is where BYU's improvement on offense starts.
