Re: NFL Dynasties
I think we disagree on the definition of "dynasty". You've got a lot of teams on there I wouldn't even consider dynasties.
For me, it's the same coaching staff with essentially the same personnel winning multiple SBs.
If you don't win a SB, it's not a dynasty. Bills are out.
If you make major changes in personnel and coaching staffs, it's not a dynasty. That disconnects Noll from Cowher from Tomlin. And it makes the Raiders, Parcells era Giants, and Redskins NOT be dynasties.
I would include the 90's Cowboys as a dynasty because, even though the coaches changed, the team remained essentially Jimmy Johnson's team.
