Retzlaff completion % is dismal vs. man coverage which Colorado plays quite well.
And Sanders is lights out vs. every type of coverage. Buffs have only lost when he's heavily pressured in the pocket. BYU ranks at the bottom end of Division 1 in sacks.
Predicting the only way BYU wins this game is executing above their heads in all three phases. Need to be +3 in turnovers with scores off each TO, 4 sacks, 200+ yards rushing/200+ passing, TOP +10 min, and hold Buffs to one +40 yd gain.
