16. Rex Ryan
First of all, let’s acknowledge the fact that Mark Sanchez wasn’t the reincarnated Johnny Unitas. However, the New York Jets needed him as their starter in 2013 but he wasn’t available. Why? The short answer is because Ryan broke him. It happened during a preseason game when Ryan made one of the strangest decisions possible and paid the price for it.
Usually, the coaching staff are very aware of their players’ fitness levels and manage them carefully during the preseason. But for some reason, Ryan left Sanchez in late into the game. His carelessness affected the Jets’ entire season because Sanchez tore his rotator cuff. As a result, Jets’ fans enjoyed the displays of Geno Smith for a season. They truly have suffered, haven’t they?
