That is probably true
BUT
If Utah beats UW, and WSU still doesn't make CFP top 12, not only would WSU not go to Fiesta, but there is a chance UW would go to Alamo and WSU drop all the way to a BS Redbox bowl, because no bowl that low has ever had a P5 10-2 team fall to that LOW of a bowl, in the BCS, CFP era.
Thats like if a P5 10-2 were to play in the CHEEZ IT BOWL.
IF WSU falls to #4 Redbox, below #3, Holiday, #2 Alamo, NY6, etc, WSU should Decline, stay home, protest, raise a stink, in the media, just like UCF did, raised a stink.
So Utah beating UW, is awesome IF WSU gets ranked 12th, goes to Fiesta
But IF that dont happen, Utah beating UW SUCKS FOR WSU,
Rooting for Utah to beat UW, and Utah beating UW is a HUGE ALL OR NOTHING GAMBLE for WSU.
Might be better for UW to beat Utah, and WSU goto Alamo, then for Utah to beat UW, WSU not make top 12, no goto Fiesta, no get Alamo, play in either Holiday, or Worse Redbox
Either way not a good position for 10-2 WSU to be in, that the BS CFP rankings put WSU in
WSU should have been ranked #12
