fan or pundit would agree that WSU and OSU are better football programs than UNLV or AFA over the last decade and over CFB history.
My guess is your judgment is clouded by some weird obsession with the Pac12 being bad and failing, which is petty TBH. But don't worry, it won't be considered a power conference.
The new Pac12 is clearly better than the current MWC and definitely better than the new MWC will be and it'd not debatable.
