Not to mention terrible for him. There's no way he can put up any stats as a Jet. What few targets he gets will be passes thrown 10 feet over his head. He and his agent have to be smarter than that.
If Decker signs with the Jets it will show he's ignorant of the Caste System, which he likely is given my impressions of him. He should re-sign with the Broncos at a discount if no teams with good QBs are interested in him. It would be a discount that would pay off down the road as he would continue to put up good stats and could sign another big contract as he's still young. If Decker goes to the Jets he'll have almost no chance, between the incompetence of Smiff and the city's hostile media and DWFs, to avoid being quickly labeled a bust.
