I'm picking a high-scoring squeaker at Cal.
Why?
Cal has lost 5 of their last 6 games. Yes a couple of those were ranked teams -- but they weren't exactly close in any of those games.
Washington State and Colorado are terrible teams. Cal barely beat both of those teams.
In all of Cal's wins, the only team that looks something like the quality of BYU is Oregon State. They lost to Washington who looks about the same quality as BYU.
As questionable as BYU's defense has been, Colorado and WSU have much worse defenses.
I think BYU will get a W in a close one.
