Well, this list is biased simply towards the length of time the team has existed. The top teams are the oldest, the bottom team is the youngest. Not much higher math equations necessary.

I am surprised the Broncos scored so poorly, even thought they are a younger team. Pat Bowlen, the current owner, is the most successful current owner, with 25 winning seasons and 5 losing seasons.

Isn't that pretty much what "all-time" means?
