All three are a bit of a crap shoot... they all have some big potential. I'd think that Jones probably has the most upside, as it will be primarily Jones, with Leon Washington spelling him now and then. ADP is going to hurt Chester, for sure. He has to. I don't see any way that they could justify paying for a Peterson and not using him. The precedent that you have there is Reggie Bush, or Cedric Benson, except that Benson was a holdout and Bush was an ideal receiving target to add to the team. ADP is going to be the #1 by next year, is my bet. Deuce is solid, but Bush hurts him.
Long term, I'd rather have Chester Taylor. For 2007, I'd rather have TJones.
BTW, you really should be posting this in the appropriate forum. You'll get more responses, and you will save your moderators some time. This is a thread for the
