As for the playbook, even Hans has pointed out several times that since the game moved to the early part of the season Utah has run minimal plays out of minimal formations, has run a very base defense with few stunts and blitzes. That part is true, the majority of the playbook isn't open for the game.
And yes, Kauai is correct at least as far as I'm concerned. I'll take PAC-12 wins over BYU wins every time. Beating BYU is still fun but it isn't as important as it was in the WAC/MWC.
