I could use the old broken clock analogy but yes it was a hell of season at 13-0. What I found interesting is Heupel went 12-0 the next season. I believe he inherited a lot of talent which Frost also inherited imo. Since it's not a P5 conference it's difficult to access coaching acumen to say the Big 10. UCF has actually had talent going into the NFL over the past 10 years. Frost put it all together and they certainly had a magic season but right now he has a losing 3 of 4 years as a HC.13-0 is still 13-0. It doesn't matter where it happened and it shouldn't be dismissed.
I'm still sold on SF and hope he's going to get things turned around at Nebraska. To be honest the 100% certainty I had regarding SF 2 years ago has however taken a severe beating this season. Just have to wait and see what improvements he can accomplish in the off season.
