David Lee was called for a flagrant one after bringing Cody Zeller to the ground as he attempted a layup, and the call was admittedly iffy. That said, Mark Cuban's only going to lose some dollars with this tweet about the play.
Again the NBA embarrasses itself by not knowing what a flagrant foul is.311 to go in the 2nd. No contact above neck. Fall down get flagrant
