This past year was interesting in the sense that it's so difficult to evaluate who was the best Pac-12 team. USC probably had the best overall season but lost to Oregon and Oregon looked like the superior team in that game. The Ducks also dropped some duds to Cal and Oregon State and didn't show up extremely well against Iowa State. UW was off and on most games and had such a small sample size it was tough to evaluate. Stanford ended on a 4 game winning streak and looked great at the end of the season. ASU and Utah ended well also.
