BYU just isn't good enough to lay this kind of number especially on the road with an early East Coast start time and being in a letdown spot following four consecutive victories. 
UMass is one of the worst teams in college football. But the Minutemen are capable of putting up points. They average 28.2 points at home. 
The Minutemen haven't played a home game in three weeks. This is their final game of the season so an effort should be forthcoming.
