Interesting little video clip here from our friends over at TMZ.com. Mark Cuban apparently has come down with a case of Kobe Bryant syndrome and doesn't realize that due to his fame, people are likely to have their cameras rolling anytime you interact with them in public.
Now we know that Mark was joking around here, and there was no actual, um, powder anywhere to be seen. I'm guessing though that this probably isn't the image that David Stern wants the owners of the teams in his league projecting. It will be interesting to see if the commissioner decides to take any action against Cuban for this less than desirable behavior.
