If the pregnancy-related allegations are true, he's one of the worst kinds of humans in the world. But for now they're just allegations in a big money lawsuit by a (possibly jilted) ex-girlfriend, so I think calling him an ass is a bit premature.
I can't say I am surprised by this. He's been average at best and just the pits in the post season. His salary and no trade clause will make it difficult, so maybe it's just something to try and motivate him?
