ESPN: Pac-12 Heisman tracker
We have a new front-runner -- at least in terms of the Pac-12 players -- in this week's Heisman tracker. Oregon running back Kenjon Barner, who was tied for third last week, has stumbled out of the top five and been relegated to the "others receiving votes" category. USC wide receiver Marqise Lee checks in tied with Braxton Miller for fourth in the ESPN.com Heisman poll. A pair of running backs -- Ka'Deem Carey and Stepfan Taylor -- also picked up some votes this week.
