"Right now I'm around 250," 49ers RB Anthony Dixon told the paper. "Me and coach talked about it. I'm gonna do some fullback stuff this year, too. I'm trying to bulk up a little more so I can handle both. I really want to be versatile, you know. That's what I'm definitely trying to do."
It's not difficult to envision a scenario in which the 49ers try to get Frank Gore and Dixon on the field at the same time in a split-back formation. But a full-time switch to fullback for Dixon is not a good fit.
