Thumbs up on any Babe Ruth/Boston Braves reference.
Take Iverson, for example. There is nothing wrong with wanting to play until you drop; we rather admire the sentiment, especially from someone who gave so many chunks of his body to the game in his prime. But this is really a low-level version of Babe Ruth to the Boston Braves, and those scenarios never end well. The Grizzlies are going nowhere, and Iverson is marching blithely along that path, just because he isn't ready to go yet and nobody he wants to play for will have him.
