It seems highly unlikely at this point that either Clinton Portis or Tiki Barber gets signed.
However, don't be surprised when a running back goes down, that teams then come a callin' to one of these guys.
As professional athletes, they're still going to be in good shape.
And most likely, good enough to somewhat contribute down the road.
All that said, if both do happen to sign, who contributes more?
Well, the answer lies ahead.
