Lmao!! He can sue for whatever he wants. If he feels the NBA forced him to sell, which they are... regardless of if he does it on his own or not, he can sue the NBA for those losses. The fact you think he can't is hilarious. Out of your league bro. I think he'll lose regardless though and that's why he'll sell the team first.
File a case without merit isn't a genuine suit. Do you not understand the difference, it will get dismissed before even having a motion for discovery being set.
