It's interesting the diverse pesonalities as well as running styles of the Cowboys' three running backs: Felix Jones, Marion Barber and Tashard Choice.
Felix, the speed guy who is a threat not only to run but catch it out of the backfield, is rather laid-back. He's not grandiose and suggests all three backs don't care about number of carries, just number of wins.
Marion Barber, for all the power he brings on the field, is extremely introverted when it comes to talking to the media. He either doesn't talk or says very little when he does.
And then there's Choice, a high-energy bowling ball who's not shy in the least to express his desire to force offensive coordinator Jason Garrett to include him in the scheme. When asked if he's OK with three backs all fighting for carries, he said: "Absolutey, I got to be. Everybody wants the football, everybody can play, so that's just the position we're in right now."
