I would trade Chad for a 1. Absolutely. I seriously doubt he is with the team next year unless he restructures, and with Kellen being in year 3 he is coming up on a new contract as well. Many here would hate it, but a CHad trade could be a great long term move for the Jets.
IIRC we'll need to restructure Chad again after this season anyway - correct me if I'm wrong, but he's due a huge roster bonus before 2008? Would be an ideal time to trade him on.
