How is that any different from now with the CL?
Manchester United are one of the worst ran clubs in football but the spending power generated by the CL allows them to keep sneaking into Europe. Any of the big clubs who fuck up spend their exceedingly larger revenues than their non-CL competitors for a few years and then get straight back in.
At the beginning of the season we could go around every top footballing nation and pick the top 3 or 4 and be right on 90% of the teams.
We're not even talking about the Super League at this point, you're failing to acknowledge that football is already broken in terms of financial power thanks to the CL. West Ham turnover about £150m if my Googling is correct. City turnover half a billion. City earn 3 times West Ham's revenue every single year. They aren't competing with us. They might win a match or whatever but in the medium term, we'll finish above in 19 out of 20 seasons. That's a disparity that is impossible to bridge on the pitch.
I think football competitiveness doesn't exist. I think the format is very broken. I think this is worse and will push it into extremely broken. But the distinction between very broken and extremely broken is almost nothing, it's fucked either way. So if it's already fucked then what are we trying to save?
