While I must hate him now that he's a Cub again, I really enjoying watching Greg Maddux pitch. He's been around for a long time now and it's inevitable that he'll be retiring someday soon.
George Will sums it all up much better than I could.
Yes, I know it's not even loosely Marlins related, but the likes of Greg Maddux don't come along often. If there was a Hall of Fame of Hall of Famers, Maddux would be in it (well, five years after he retires at least).
