Very few athletes (or people for that matter) have been able to turn around public perception like Alex Rodriguez.
One of baseball's favorite villains during his playing days (you know, the steroids and lying and all) A-Rod is now viewed by many as a pretty likable guy. Some of that certainly has to do with him dating Jennifer Lopez.
Apparently, for a segment of the population (young females) he's now best known for being JLo's boyfriend than one of the greatest baseball players of all-time.
