Do You think Betts is Expendable?

[Trample the Elderly]

I'd like a bigger RB like Brandon Jacobs or Marion Barber to run up the middle and let Portis cut up the sides like he was meant to do.

I think Betts would be a better ball carrier if he got more carries. Portis and Betts fumble every once in awhile although it's usually when we really don't need it.

Betts isn't expendable unless there's an upgrade waiting to take his spot. Mason has the same kind of build as Betts and Portis with the latter two having a few more years in the weight room. With Mason we're just getting a younger Portis or Betts without the experience, bulk, or skill. I do like him though.

How about this one? Which RB would you most be willing to part with and why? What Sayeth the Mob?
