I actually don't think they are overrated, from what I have seen they are VERY physical on defense, and very athletic on offense. Their defense reminds me of high level SEC D.
Keep an eye on the the Hawaii Rainbows, I think they will run the table and play in a BCS game and win. They have 3 tough games left, Fresno St., Boise St., and my U of Washington Huskies. All three are at home though, tough to travel to Hawaii and win. If you get a chance to watch them, it's quite a show.
