The fact that he's in his late 30's has absolutely nothing to do with it, right? It does. But his decline has been alarmingly sharp compared to most sluggers of his magnitude. This leads one to wonder... With some sluggers, they just gradually decline until they can't find a job anymore, or retire. Some just hit the wall. McGwire, Mays, etc just hit the wall. Decent one year, then terrible the next. Sammy was one of those. Its probably not the best idea to reference Mark McGwire as an example of an aging star who hit the wall as opposed to someone who used steroids. True, but my point is made. Your point is mde that one of your examples is a guy who hit the wall suddenly and was a user?
