3. Rich Kotite
After a 6-10 season, the New York Jets sacked future Super Bowl winner Pete Carroll and brought in Rich Kotite. Furthermore, they took the dangerous step of making him general manager as well. If it goes well, then excellent. But if it doesn’t, one man will run your franchise into the ground with nobody there to challenge his decisions until it’s too late.

In sum, that’s exactly what happened with the hapless Jets’ coach. He led them to the two worst seasons in franchise history, with just four wins in two years. His final season saw the Jets finish with just a single victory. Also, his efforts in the draft were as shambolic as his coaching. His name still makes Jets’ fans shudder today. One of the worst coaches in NFL history.
