See my #2 happens to be Frank Gore. I made a pre-Week 1 deal to get Gore and Bruce for Favre and Willie Parker. Parker went off unexpectedly, but Gore was solid and I already had Romo so Favre was just a trading chip for me. Bruce may be good for a spot game or two, but I already have 4 RBs on the roster with Addai, Gore, D Mac, and Chris Johnson. Should I bail on Bruce and grab another back or WR or TE to stash for Witten's bye week?
