If the Pats had to go into next year with the same roster that they have now but they got to add any ONE NFL player to the team who would you want? Maybe a young 'shut-down' CB like Darrelle Revis? Patrick Willis. The best young (hell maybe the best period) ILB in the game. A pass rushing force like DeMarcus Ware. A legit weapon at RB like Chris Johnson or Adrian Peterson. For me it has to be the RB and the RB has to be a work horse. If the Pats had a guy that could grind out the tough yards, keep the chains moving, keep defenses honest I think the Pats would be elite even with a weak D. I think we all remember when we had 'Clock Killin' Corey Dillon. His speed was going by the time he got here but he still was horse. The player that I would take is Peterson. While the fumble issue concerns me I figure if Tiki Barber can be thaught to hold on to the ball Peterson can too.
