Washington will not in my opinion go undefeated. They have three road games they can easily lose. Don't put much into the win at Oregon. The Ducks are a mess. Their coach is all but gone. Look at the road game UW played at Arizona. It went to overtime and the Huskies were fortunate to win.
The three teams they have to play on the road are much better than Arizona. Utah is going to be tough and I'm actually going to predict a UW loss here. California is another game that can get away from UW. Call has a big time offense that's much like UW's. Davis Webb will throw for over 4,000 yards. If UW is still unbeaten when they play Cal, there's going to be a lot of pressure in what will be a very high scoring game.
But still, if they're still undefeated when they play Washington State, this is where they will lose. WSU is the one team that has the ability and the motivation to end UW'S undefeated hopes. I could see UW losing this game and then the PACK 12 championship game as well.
And they still have home games against two teams playing much better than earlier in the season in USC and Arizona State. A surprise home would not be shocking.
These teams UW has to play are not Duke, Virginia, BC and Wake Forest. More like UNC, NC STATE, and Virginia Tech. Louisville has a much easier chance of winning out than Washington does.
