When general manager Mike Maccagnan arrived two years ago and, to much fanfare, signed Darrelle Revis and Antonio Cromartie together again, he was interrupting what had long been a plan to reassemble the Jets from the ground up. Maccagnan's predecessor, John Idzik, was brought in specifically to clean up the team's salary-cap space and increase its draft capital -- something he did almost immediately. When the draft production did not meet expectations, the franchise took a hard right turn back to the Rex Ryan days -- quick, flashy veteran signings to bandage the real, significant issues. The question now is whether Johnson will stay the course. Should the Jets struggle in 2017, there will be a strong inclination to clean house and start all over again. But a youth movement is rarely fun or easy.
