After last week the offense is ranked 125 out of 130 overall according to S&P+. The defense is ranked 41 overall.
Is the defense spectacular? No. But they are better than average according to S&P+. They held UMass to 16 points - 14 points below their season average. That should have been good enough for a win.
EDIT: The defense played well enough to win all but two three games this season - LSU and Wisconsin LSU, MSU and Wisconsin.
The reason this is the worst BYU team in 60+ years is because the offense is completely inept. Injuries and suspensions have certainly played a part in that, but you are kidding yourself if you can’t accept the fact that the biggest problem is coaching.
The entire offensive staff should be dismissed after next week.
