While a freshman, it seems more and more freshmen are stepping up and having big seasons. He could be one of those guys. If he does well and then they have Perkins, they could still be plenty dangerous.

But I agree, I'm worrying more about other teams.

Another thing, it's not just that they're returning a lot of guys, you also have to pay attention to how young they were. If they were good with a bunch of freshmen and sophs, they could see a big jump this year.
Likewise, people seem to forget that about BYU as well. Sure the defense sucked, but I'm willing to give some leeway considering how young our top talent core really was. BYU had a TON of freshmen and soph contributors last year.
