Though do note--The majority of the league doesn't budge on this and the NYJ won't cave. They are one of 30 teams that simply don't do contracts without offset language.
Wilson is using the leverage likely for a bigger signing bonus upfront. All at the expense of valuable time w/ the team and dragging this into the public eye. Just an odd way to start out. Strikes me as a pretty picky upfront signing tactic but whatever floats his boat.
