the estimate on the expansion fees is pretty vague....2.5B-->5B+ per team. If you assume 9B for two teams, then each owner would be pocketing 300M. And I'm assuming some advantageous tax treatment since this is supposed to compensate for future 'lost' revenue
the Media contracts were initially a 76B/11-year aggregate deal. But I read where there has already been some streaming revenue internationally added to that. So then, call it 7B/year. The owners get half of that, at least I think that's their cut in the new CBA. Call it 3.3B/year since the league office will skim some off the top (and it makes for easy math). For each of the 30 owners, that's 110M a year. If there are 32 owners, that drops it to 103M/year. A loss of about 7M/year. But this is year 3 of the new CBA and if expansion doesn't happen till 2027, there would only be 7 years left on the medial deal. So, a total dilution of around 50M vs a 300M infusion in say the 4th year of the deal
so I take back what I said about owner opposition because of dilution. Those expansion fees are pretty persuasive. That's not to say there won't be any opposition though
there's also the factor that while NBA teams get to keep most of the revenue from home games, there is still a portion that is dropped into the BRI pool. I tries to find how much or what percentage but it's all pretty vague. In any event, and maybe it's not very significant, those two expansion teams would be dropping some money into the BRI pool that would offset the dilution
