Their DL is extremely thin right now (thinner than ours) and they are ranked 100 in total defense. They would have to play out of their minds to slow down BYU's offense. BYU would have to lay a massive egg on offense to not score more than 30.
The question is if A) our defense (also somewhat short-handed) can keep USU from sustaining drives and B) we don't give up unnecessary turnovers.
