There is no anti-WSU conspiracy. Refs are not for or against any team.
But referees are human beings and they understand how a game is
supposed to go. To protect their credibility, there is a
default setting for close calls even before the game starts so that one team gets the benefit of the doubt on tough decisions. To wit:
- Stanford makes a BCS bowl every year, and they're bulldozing their way through the PAC again, 5-0 in conference. Little ol' Washington State's Ivan Mclennan strips Christian McAffrey and recovers. Zapruder film shows a clear fumble recovery, but refs confab - and vote for Stanford. It's worth 3 points to Furd and they only needed 2 to win.
- Oregon's Dior Mathis wraps up Isiah Myers like a mummy late in a game on a 3rd down conversion strike from Connor Halliday. Refs felt it was a judgment call and keep their flags. Clear PI, but they had some doubt, and this is Mariota-era Oregon. Ducks go on to win by 1 TD.
- USC, this year. No need to recap - you get the point, but we again lose by enough
- Can't recall the team, but several years ago there was a home game where Wicks (?) dove into the end zone but was ruled down at the 1. That one was legitimately a close call but the Cougs just don't have the reputation to pull it off, and they lose.
We're just in this frustrating era of football where we're not a legacy team, and we haven't been good for long enough to command the benefit of the doubt, or to be expected to win vs other conference teams. As a result, we lose perhaps a game a year to a team whose fortunes rode on a reputation built 5 years earlier.
I think there are other 'cheats' used by referees as well. The game gets called based on who is supposed to win, but refs
also do make-up calls as we all know, and very often you'll see them start calling it favorably for the underdog if the hero gets out in front too far.
Not a conspiracy, just an unfortunate fact about human nature and how the underdog's fortunes are decided.
