Oregon State's title chances dropped on their loss to the Huskies (woo!)
Oregon keeps rolling toward the Pac-12 title game; losses from their three nearest competitors certainly helped. Interestingly, Oregon's Sagarin rating took a small hit and as a result their chances of going undefeated also took a small hit.
UCLA and Arizona forced themselves into the Pac-12 South conversation with big wins, making my life much more difficult by:
a) Adding to the number of 3 and 4 ways ties the model needs to adjudicate and
b) complicating my graph.
