4. Vance Joseph
The Broncos weren’t exactly worldbeaters when Joseph took the reins, but he ensured that they wouldn’t reach that status. After back-to-back losing seasons, he received his marching orders. That was an extraordinary achievement in itself because it was the first time in over 40 years that the Broncos had two losing seasons in a row. He ran them into the ground.

Joseph’s shocking in-game decision-making and inability to manage the clock in clutch situations made fans loath him. Furthermore, he struggled to motivate his players and also put too much faith in underperforming athletes. Nobody shed any tears when he departed. He may get another chance to prove himself in the NFL but it will definitely be a gamble.
