What I remember about him was that he had a severe and undiagnosed medical problem that affected his pitching, which he reported, and was accused of being a slacker. Then the condition damn near killed him.
At one point he was homeless but I think some people from the Astros rallied to help him out. An all-time Astro who really played in the Astrodome.
i believe it was a stroke..i remember that...very strange....
