Our schedule isn't one of the hardest in the country. It was in the pre-season conference season when most teams are beating up on FCS teams, but won't be in 3 weeks. If every team had lived up to their pre-season billing, it could have been really good, but it's really not. Teams now: Utah is legit. Boise, USC, and Washington are like 25-40 range, Tennessee slightly lower.
We had a great home schedule, but USC, Tennessee, Washington, USU, USF have all been worse this year than they were expected to be. 3-2 against teams ahead of us in FPI is really good, 2-2 against teams behind us, not so good. So it's a bit of a wash.
