I would agree at this point in the season that is how the situation looks BUT at the same time, the season is only half over! If it were that decisive then the Playoff Selection Committee would choose the Final Four right now.  I am going to bet all the remaining unbeaten teams will not remain that way by the end of the season. Plus, and I while I do not think you meant it that way, are you suggesting by your comment that once there are only 1 or 2 unbeaten teams remaining in the Pac-12, the other teams should just quit against them in order to make sure they stay unbeaten in order to be considered for the playoffs?!

Personally, I am not sure what to make of the Pac-12...great depth or no team able to "drive it home." WSU looks unbeatable and then does not even score a TD against Cal? Cal looked slow against Oregon; Oregon looked slow against WSU; WSU looked slow against Cal! We will see!
