For those who are into watching documentaries of any sort, there is often nothing better than one done really well. The Last Dance, dedicated to the Chicago Bulls of the Michael Jordan era, was exactly that.
For fans of the Denver Broncos, a good documentary right now dedicated to a player (or important figure) from the team's history would be a welcome sight on the television.
The Broncos have one of the most storied histories of any team in the NFL. As such, there are many candidates to receive a documentary on their careers.
