The running game is extremely important in football.
It takes time off the clock to secure a team's lead in a tight game. It wears down the opposing team's defense. It opens up the passing game.
Last season three Pac-12 running backs were among the top-10 rushers in the country: Arizona's Ka'Deem Carey, Oregon's Kenjon Barner and UCLA's Johnathan Franklin.
Barner and Franklin are gone. Carey's status is a work in progress. And there are a few other teams with question marks in the backfield as well.
Who is set at running back? Who has too many horses in the stable?
And who has a legitimate Heisman candidate ready to be unleashed this fall?
