"wilt down the stretch is all bull" and that is all what Pomeroy calculates into his "luck factor" which tends to even out over time.
And over the years he proven to be right about that. A couple of years ago when everyone had the Lobos of New Mexico ranked very highly, he had them about 50 spots lower and they proceeded to demonstrate their proper level in post season.
BYU is much better than its record without decent bigs. If Austin, Aytes, Winder and KC return healthy, they will be dangerous to good teams.
