We've seen so little of Jones and Choice, but their potential is sky high.
Jones has that one-run TD potential everytime the ball is in his hands. Choice though, IMO, has the potential to be a Westbrook type multi-weapon player. With what I consider (as do many others) limited talent at the WR position, I think using Choice out of the backfield could really jolt the effectiveness of the passing game. It can also open up the playbook by putting him AND Barber or Jones on the field at the same time.
Frankly, I think the more these three handle the ball, the better off this offense may be in 2009. The options are exciting and make the anticipation for the new season SO awful to endure.
