My prediction: Josh once again spurns all these opportunities and re-ups for another year with the Patriots.
Obviously, if his internal head-coach clock is ticking super fast and tells him now's the time, he's going to leave after this season. I just think he's super happy with his situation in New England and knows that as long as BB and TB are with him here, unlike a lot of coordinators whose candidacy goes hot and cold from year to year depending on how their team does, Josh can essentially pick his jumping off year/situation.
