The interesting part to me is the idea that the super League would be just for football. Honestly, I'd be happy about it. Would hopefully allow the rest of the sports to align in more geographically sensible leagues hopefully. Only question mark is whether basketball would affect that.
Trouble is that football revenue would be shared with basketball to make that lopsided as well. If you could find a way to limit how much is spent on those non-football sports, then maybe. But even if that’s how it starts it will not stay that way. Either the media partners or courts will ruin it. And then once you agree with the alignment to start, you can’t back out when the money gets out of whack.
