You talk about P5 like it’s all Clemson and Alabama. It is not. It is also Rutgers and Kansas. The are plenty of FBS teams that SDSU would be favored to beat, including a few P5.This assessment isn't fair.
SDSU is a legit top 5 team in the FCS -- which yes of course, is minor leagues compared to the Big Ten.
But, if you take a look at top 5 FCS teams playing P5 teams, I would be interested to see the average results. I doubt they're all blowouts, and wouldn't be surprised to see some close games.
It's a no win for the Gophers. Win, and you were supposed to, lose, and the sky just fell on your head.
On the DI FCS side, there is also 125 teams, some with no scholarships. If you schedule and blow out an FCS team, the question is always, which one?
