I agree with anae4anae in the sense that it wasn't ALL "luck." They're obviously things that can happen at any time in football. They were definitely fortunate though.
However, I completely disagree with him that Houston is a team capable of putting up 46 pts against us again. Having that many rare things all happen to go your way in one game, and still lose...
They can be dangerous but their team only scores in the teens/low 20's (our season defensive average or lower) without all of those things including a KR, pick 6, OPI TD, etc. Not a fart's chance in the wind that they light it up for an offensive shootout in Provo.
