Notice those are all bottom feeder teams, the only two of which who’ve made the playoffs recently largely doing so because somebody has to win the NFC East. I think all those teams are under 500 for the 21st century, most WAY under. Plays right into what I said, watching your team get killed isn’t fun, especially not when it’s expensive.
Of course with all the money they get from the TV contracts, attendance is really pure gravy money.
Which begs the question of why they need to put any teams in Europe at all instead of just cutting deals with European networks to broadcast NFL games.
