Nothing like the popularity contest known as All Star Game voting to drive an attentive fan crazy.
The All Star game is meant to be for the fans, so logically, the fans should get the right to choose who they get to see in the game. As a result, many times a "fan favorite" makes the game despite lackluster performance, thanks to the fan vote.
While the differences between good and bad have become more clear as the years have gone on, there are still plenty of whoppers on the ballot.
