If Wisconsin wins the B1G, they're in. I don't get what that's so hard to see.
Washington does not have a signature win. WSU is not a signature win. The only other team they played was USC, and they got beat. If you watched any of the PAC 12, its mediocre at best. It's a very top heavy conference,and none of them stepped forward with quality non-conference games.
The Wisconsin win over LSU is better than any win Washington has on their schedule. LSU has 4 losses, all to teams in top 15, and they're the only team to give 'Bama a game.
