No they wouldn't. Wazzou played a bunch of 75 and worse rated teams. If you think they have a better resume, you must think the Big 10 is worse than the Big 12 and ACC.
Write out the opponents. It would be easily spelled out for you. Are you trolling here? The Wazzou love fest is kind of insane.
Portland State--they stink. About on par with Kent State.
Texas Tech--as good as anyone PSU has beaten. Just beat undefeated Iowa State (who beat Iowa).
Washington--also on PSU's schedule. Did they stink then, and are good now?
San Jose State--not as bad as you think. On par with Wisconsin.
Boise State--playoff team. Argument can be made that they are the second best team in the country.
Fresno State--run of the mill. On par with UCLA.
Hawaii--stink. Kind of like Bowling Green.
San Diego State--another run of the mill team like WVU.
Remaining teams are Utah State, New Mexico, Oregon State, Wyoming. Not unlike playing Maryland, Purdue. I'd say Minnesota is better than any of those teams, but let's not act like it's a huge step up. It's Minnesota.
So there you have it on schedules. About on par with PSU's. A little easier. Not sure how you can argue that. Southern Cal and Illinois probably a bit better than anyone on there except Texas Tech, who I'd say is about even. I'd say PSU's strength of victory might slightly overtake Wash State.
So if we are comparing a 1 loss WSU vs. a 2 loss PSU, I'd say it is very close. Would side with the team with only 1 loss when there are no high quality victories.
