Last year, I think It's been a lot longer than that. I'd guess a minimum of 4 years. It never forced him to miss any time while he was with the Cards, and I don't think it was as bad as it's been lately, but it was something that was talked about pretty regularly. ETA: According to Wikipedia, he was first diagnosed in the second half of the 2004 season. Wow, I completely missed that. I knew of his other health issues, but was completely blanked on that when I, like TT, was big on signing him.
