Where did you get that idea? That isn't what Woj said. He said that other teams around the league are concerned and have questioned how the Suns are doing things but that's it. He said that James Jones is running things right now, which isn't anything new, and how there has been talk of him hiring someone to oversee basketball operations but they haven't interviewed anyone or even made that decision for sure. He even said that Sarver is at a crossroads again, not the league. There is no precedence for the league to do anything. It would be the first time in NBA history that they stepped in to save a franchise from their own bad decisions.
I don't know if that's ever happened in any of the other big sports league but I don't think it has in the NFL or MLB. I know the NHL has taken over teams that were in trouble financially but the Suns aren't losing money so that's not an issue here. I would think if the NFL ever did that they would have considered it under Bill Bidwill's time as owner of the Cardinals because they were awful for a long time before his son took over and they got their new stadium.
