Tough call. At least CJ2K is healthy. I think he will bounce back, so it may be a good time to buy him low because i can't see the Titans giving up on him this season.
If Bradshaw was healthy I would think harder about the trade. I own CJ in a league and I would want more for him than a banged up Bradshaw. That said, I'm giving him one more week before I get nervous.
