At the time of the extension we failed to go with the whole committee backfield approach that was starting to sweep the NFL. Its not on 1 guy anymore its normally like 2-3 guys. I think that you need a power runner, a speed runner and someone who can be a scat back/receiving back. Id like it if Dallas could extend Pollard(at a modest price of course) and find the other 2 backs to complement him. He can either be our scat/receiving back or our speed back
