I'm intrigued based on rankings from last week.
Their offense (#26 FEI) is better than BYU's offense (#33 FEI).
Their defense (#61 FEI) is the same as BYU's defense (#62 FEI).
Their special teams (#79 FEI) is worse than BYU's (#47 FEI).
Under S&P,
Offense: BYU (#35) is ranked higher than Cal (#41).
Defense: BYU (#61) is ranked higher than Cal (#87).
Yet again--I think it all comes down to turnovers.
They're fighting to get bowl eligible, so it'd be great to keep them out of the "post-season."
