Star running back Ka'Deem Carey of the Arizona Wildcats (and Canyon del Oro before that) is expected by national college football analysts in 2013 to build upon the successes of 2012 when he set an Arizona record for yards gained in a single season and was a unanimous AP All-American after being named to eight such national teams. Carey ran for 1,929 yards to eclipse former record-holder Trung Canidate's 1,602 in 1999. Here's a look back at highlights of Carey's 2012 all the way back to his time as a prep star in Tucson.
