A nice blast from the past from Fire Joe Morgan (about a different knuckler, but the point stands):
The relevant quotes:
Wallace: His knuckleball, or whatever you want to call it, is a bigger menace to the game than steroids, growth hormone or Clomid will ever be.
If as many guys in major-league baseball threw the knuckler as have taken performance-enhancing drugs, the game and its fans would have died of boredom years ago.
Someone needs to remind him of this on twitter (@ESPNNYYankees)
