Watching him the championship game has left me not impressed by Rod. It seems like at this level he's using his size more than anything and on defense he's more prone to take plays off than go hard.
I think it's hard to really gauge him as a pass blocker because there is no really great DEs in Nebraska in Class B.
He does show that he could play at Nebraska because once he gets his paws on someone, they aren't going anywhere.
Maybe I'm just not good at evaluating line men but that's what I see. I'll just wait until he gets into Nebraska's weight program. One of the biggest things he needs to work on, IMO, is his foot speed. He just looks slow anytime he moves past the initial point of attack.
I do think that he's going to be a beast once he gets everything together and plays against tougher competition.
