The 49ers really only have 1 true full back on their roster - Bruce Miller. His primary back up is Anthony Dixon. We know Dixon's roster spot has been on the bubble the past few years - and although Miller has done a good job at fullback, the 49ers quest for versatility, and Miller's lack of it, could put him on the bubble. Of course Frank Gore may have a thing or two to say about that.
