Going off my lousy memory here, so please correct if you remember this better than I.
A few years ago, when the steroid craze broke, some talkshow guys (in NYC?) were talking about how Bagwell must have been a user, as they were looking at some before and after pictures. His wife called in and yelled at them for saying it. She said that she and Jeff had talked about it over the years but he didn't want to jeopardize their ability to have children.
Obviously it doesn't prove anything one way or the other, but Bagwell and steroids always brings back that story for me.
