The biggest play of the game was BY FAR, the poor decision and poor throw by Wilson on that pick 6. 

That play was where BYU lost it, and Utah won it.

If the QB rating does not reflect that, for whatever reason, then it is flawed - which is probably why KWhitt rarely if ever mentions QB rating, but he ALWAYS mentions turnovers - it has a much greater effect on win/loss than QB rating does. That said, I am sure he would love to improve the passing game at Utah - he is getting there, although gradually, and slower than we'd like - but it is happening: Troy Williams was better than Travis Wilson. And Tyler Huntley is better than Troy Williams, etc.
