Lots of people have talked eloquantly about the monetary greed the Super League entailed, but I think it misses the wider point, Kronke (et al) have long been pushing for a _redistribution of power_ in football, away from the 'leagues' (e.g. the Premier League, La Liga, UEFA) to the clubs and owners themselves. Which is the now the canonical model for US sports, where they're most comfortable. Another example of this…
If the US had relegation from baseball and football it would improve the sport. At the moment there is no penalty for coming last in the AFL or NFL :-) oh and next year you have first pick of the best new players
The NFL, MLB, and the NBA are all higher revenue sports than the EPL. Even the NHL brings in more revenue than every other sports league than the big 3 North American sports + EPL- 30% more than La Liga or Bundesliga. So if revenues for sports without relegation are so much greater than the revenues for sports with relegation, why would it improve the sport?
