They aren't just losing to their biggest rival, they've gotten blown out in each of those games. Petersen knows how to defend the fruity tooty pass 70 times a game and play no defense soft as butter Leach
Have you ever been to Pullman? It's god awful and you will be hard pressed to ever consistently win up there, nor get a better coach to start there. He's not going to her fired, he will eventually leave on his own. Leach has given them something reliable on the offensive side but inevitably teams can shut down lesser talented foes. UW takes serious pride in beating the shit out of them so that may not change soon, but I will credit him in making the program consistently respectable and this coming from a UW alum who hates that shit hole school.
