Denver Broncos – Daryl Gardener
Recency bias might cause fans to point the finger at Russell Wilson after his nightmare first season in Denver. But then there’s Tebow, who had one of the wackiest careers ever. But they don’t come close to Daryl Gardener who is surely the worst player in Broncos history. He arrived with a massive reputation but departed with a cloud over him.

The defensive tackle built a strong reputation during his days in Miami. This prompted the Broncos to offer him a $35 million contract to lure him to the “Mile High City”. He had 15 tackles for the franchise before a pair of scandals killed his career. First, there was a parking lot fight and then he head-butted his girlfriend in another horrible act (via Bleacher Report).
