Yeah, it's possibly a Mark Cuban stunt BUT you have to give the player credit for pursuing his dreams.

He may just be at a stage in his life (early on) where the MS is mild. And Tysabri does keep the disease at bay for some folks. Remember that everyone's MS is different.

Anyhow, I just liked the story of this player's personality and fortitude. He wasn't going to let MS get in the way of his dreams. Maybe he'll fail eventually or have a short lived career, but at least he tried!
