I'm not into the sports pop-psychology stuff so I'll go with 5 wins because that's how good I think the team is.
Looking at the schedule:
Nearly certain win: Idaho State
Likely win, but we've seen how those play out...: CSU, Oregon State
I don't know if they are any good this year?: Washington State
Won't be favored, but could be close: Arizona State, Arizona, Utah
No: Michigan, Oregon, USC, Stanford, UCLA
My inclination is that we should win the first four listed and, on average, take one from ASU, Arizona, Utah. I'd say the chance of taking 2/3 from that group is (at best) a wash with the possibility of dropping one of Oregon State, Washington State, and CSU. That puts us at 5 wins. I don't expect us to lose to ISU and I seriously doubt that we beat any of Michigan, Oregon, USC, Stanford, UCLA.
I think that the WSU, ASU, Arizona, and Utah games collectively determine whether or not this is a good season. Unless they lose to CSU or Oregon State early... then all bets are off.
Really, I think I am being a bit generous here with WSU. They might belong in the same category as ASU, Arizona, Utah...
