Cuban is straight up lying about how he might need to sell his basketball team. Or he's lying about how much stock he owns. Either way he lacks credibility.

He may have stated the need to sell his team elsewhere. I seem to remember reading that but it was possible I was jumping to conclusions.
That said, I think it’s entirely reasonable to believe him when he claims not to have enough cash to pay the tax.
Again, I find it weird how some people think about this subject. Everyone is so intent on accusing billionaires of being liars.
