The Daily News reports that the Jets are trying to resign TE Ben Hartsock. PFT says that Hartsock has agreed to terms, but no other outlet has reported anything.
Laveranues Coles also remains a possibility for the 3rd receiver job, though the Jets will probably take their time and make a move after the draft. It's a long offseason, and Coles isn't the ideal option since he'll be a one-year stop-gap. The Jets would probably prefer a younger option, one who is a better fit in the slot. But Coles might be the best option out there who only costs money, so there's a good chance of this getting done, especially if New York can't find a solution in April's draft.
Meanwhile, DE Marques Douglas is drawing interest from a few teams, including Denver. The Jets would like to bring him back, but if another team overpays, it would allow them to sign an unrestricted free agent of their own. However, they might not want to break up the defense more than they have to, so we shall see.
