I agree. There is no "right price" here. What would they be shopping for? QBs are next to impossible to come by. There is nothing I would take in return for EJ at this point, with his potential.
If we traded him and he ended up starting for another team and winning games...I would seriously consider jumping ship.
Edit: I know we have Tyrod in the mix but he is not proven, obviously. If EJ is traded, it's next year.
