8. Daryl Gardener, Denver Broncos (2003):
Simply put, Gardener exhibited the traits and talent of an elite NFL defensive tackle throughout the first seven years of his career with Miami and Washington. His size was a fearsome task for opposing offensive linemen.
However, things took a turn for the strange when he was signed to a seven-year, $35 million contract in 2003. The fact he had five tackles in five games for the Broncos was bad enough. But add in the fact he supposedly removed himself from games and reportedly had multiple incidents with teammates, and Gardener’s goose was cooked. He never played another season in the NFL after 2003.
