Doyle's a scumbag?

[ChicagoTroy]

I've heard a few respected posters say some negative things about Doyle Brunson lately. Knowing just about nothing about him other than what I've seen on TV and reading about his history with other Texas players, why is that the case? PM is cool if people would rather not publicly say, but I can't seem to find anything different from what I've read about other poker "celebrities."
