Fair. I don't necessarily think that the offensive line is "dominant", but I do think that finding competent OL in college is NOT easy. Texas' OL has allowed 18 sacks (yes, I know it is a flawed statistic) and LSU has one of the worst rushing attacks in the SEC, so I'd have trouble saying that those units are light years ahead of Miami's.
More than anything I think it is worth reminding ourselves that three years ago, our OL was manned by guys who looked like me, now we have real size and competency upfront, which is better than most could hope for.
