Ted Miller Some notes to get you through the hours until Saturday. Thanks to ESPN Stats & Information for many of these numbers. Colorado leads the series with Arizona 13-2, but the Wildcats won 56-31 last year in Tucson. The Wildcats did lose 49-29 to the Buffaloes in 2011, the last time they were in Boulder and their first meeting as members of the Pac-12's South Division. Arizona RB Ka'Deem Carey now leads the nation with 161 yards rushing per game. Originally posted by ESPN.com - Pac-12 Blog Click here to view the article.
