The rule: "All umpires will, during spring training, be forced to stand in the batter's box and swing until at least one hit leaves the infield. This shall take place during home team batting practice."
I think this is a great idea. Baseball players are whiny primadonas. They have no idea how difficult it is to 1...get the call correct, and 2...deal with their little punk a$$es. Maybe if the players were forced to do it themselves, they'd get a better understanding of how difficult a ob umpires have.
