Another way of looking at this info.
The Bucks are not exactly lighting the world on fire with their attendance numbers. I suspect the last thing they want to do is alienate their fans with a player's behavior.
When you're a dude who's twitter picture is this:

And your twitter handle is "Nappy Gilmore"
And you tweet things like:

Nappy Gilmore ™ @LarrySanders Dec 5

There is, rightly or wrongly, PR involved. It's much easier to let this stuff slide--in the sense that its alienating to a substantial part of the NBA's fan base, not because there's anything inherently wrong with any of it--when you're on a 50 win team. When you're a 7 win team, then it becomes a problem.
