The Jets officially placed the non-exclusive franchise tag on Hall (knee) on Tuesday, Eric Allen of the team's official site reports.
It was initially reported that New York would place the franchise tag on Hall, but the non-exclusive variation allows the running back to negotiate with other teams. The Jets will retain the right to match any offer and be entitled to two first-round picks as compensation from any team he signs with, a prohibitive enough cost to make any such deal unlikely. Still, Hall's ability to negotiate with other teams could open up trade possibilities in the event that he isn't able to reach terms on a long-term extension with the Jets by the July 15 deadline.
