That's a lot yes but I think that most of them are going to taxes, commissions of their agents, etc. And it's possible that he has saved a bit but then don't have managed to be financially well.
It's a common issue for many NBA players and athletes.
Then I guess he has to adjust his lifestyle as he is not making this huge money anymore. Let's say he has to pay for the expsenses you've mentioned, say 50% was for that, then maybe he was able to keep $30m in his career in the NBA, that's still a lot of money if he was able to manage it right.
NBA is truly purely business, if you don't play your cards well, you'll end up not getting a team.
So back up plan is always necessary, like having a livelihood after basketball, easiest is to start a business since he was able to raise a capaital.
I don't know about his figures but that's for sure that he's still bagged a lot of money during his entire career run. But if it's with spending habits that are too bad for him, there's no help with that.
Most of them will realize that they did the wrong thing when they're on their peak of their careers. But then, after all of those bad spending habits or when he's a giver to all of his relatives, he gets back nothing.
Poor guy, but I hope that there's a redirection and will still have some opportunities that will come for him.
