Their record may be a bit deceiving. They have lost 8 games, but they were in all 8. Most of the losses were by less than one score. Their worse loss, to Mississippi State was only by 11 points. They only lost to Tennessee by 3. I think it is unrealistic to think that BYU is going to blow them out or even win by double digits.
Here are UMass' scores.
