This is more of a fantasy scare than anything else I think. If Jones-Drew doesn't get a new deal he is not going to play hard. He might come back but I wouldn't expect anything amazing. The Jags went 5-11 last year even though he was a top producing back. The rest of their offense is so bad that even with the 2nd best RB from scrimmage they didn't win a lot of games so they clearly need to focus on other issues. It's not like they could do much worse without him.
