I don't think it's about accomplishment, I think it's about buying time and finding the perfect situation. UCF was PERFECT for Frost. He couldn't lose. If he stays, whatever he does will look impressive. Then he's in Petersen territory when he was at Boise, where he can find whatever job he wants.
For those of you that have kids, remember when your first was born. Would you want to land your dream job when you were that sleep-deprived? He can sleepwalk at UCF and look like a genius. Maybe he wants a couple more seasons of that.
