At the end of the 2012 season, the New York Jets made a critical mistake. They could be on the cusp of repeating it.
At the time, general manager Mike Tannenbaum and head coach Rex Ryan were both on the hot seat. The Jets were coming off a miserable 6-10 season, seemingly a low point after back-to-back AFC Championship appearances followed by a competitive 2011 season.
Rather than letting both Tannenbaum and Ryan go, Woody Johnson chose to fire the former and keep the latter. The Jets ended up with a lame-duck coach working together with a general manager who did not hire him.
