there is no rich individual paying 2.25 billion just to acquire a toy
that's a ton of money for even the richest people in the world.
portland and dallas are much cheaper teams, to put this in perspective, they probably went for 300M when they were acquired, and say cuban lost 20M a year ever since. That comes out to about 500M, which means he probably breaks even if he wants to sell.
when paying 2.25 for MLSE, you do it because it's cash cow. If you turn that cash cow into a losing enterprise, not only you lose money from operations, you also lose (much more) when the MLSE drops in value. If MLSE was to drop to 900M or so (which would be the average cost of a NBA + NHL + MLS franchise set), that's a 1.35 billion loss
So, ultimately, the only thing that could make us into a dallas/portland type of franchise would be for somebody rich to buy just the raptors. And that would never happen.
Still, by having the team owned by a big local corporation, at least you know the team isn't going anywhere which is more than I can say about a few unlucky current nba cities today ...
