Keep in mind, some of the teams that had a little longer than average times in stadiums were higher recenue teams like Dallas, Chicago and the New York teams. Then there's the Packers, who I did not address, who are the one publicly owned team. The California teams mostly all suffered due to the state's budget crunch, which long hindered the state from funding new stadiums.

I also forgot Seattl, which opened the Kingdome in 1976 which hosted the Seahawks until 2001. Age at replacement: 25 years.

Buffalo has played in their current stadium since the 70s, and are currently in the same position we are in. Their owners have been asking for a stadium upgrade.
