No question in my mind that Washington State is the play. . . if Arizona had the firepower to stay in this one, I'd say lay off, but they haven't proven they can hang with any team that has a decent offense. Should be much like the Oregon game. . . the Cats may hang around for the first half, but typically fade away in the second.
Best bet for me would be to buy this down to 9.5, then sit back and hope you never needed the point in the first place! You probably won't, but wouldn't hurt if you plan on pounding this one.
