New York Jets
Adam Gase is arguably the worst Jets coach ever, never mind the weakest since 2000. He led the franchise for two seasons and ran them into the ground. Meanwhile, he destroyed Sam Darnold’s confidence after the Gang Green placed their faith in the young quarterback. The lesson is never to listen to Peyton Manning’s coaching advice (via SNY).

Meanwhile, Rex Ryan exists on the other side of the coin. There’s no pretending that things didn’t sour for him in New Jersey. But he brought them to a couple of AFC Championship games. Sometimes he rubbed people up the wrong way but the fans appreciated him when he was doing well.
