If you think balls and strikes are inconsistent - the spotting of the ball in football is awful. The idea that a chain is the tool of measurement for first downs is even crazier.
I can see it now - the umpire starts to spot the ball. He puts his hand to his ear so he can hear the operator a little better through his earpiece. Th operator tells him "A little more.....a little more....just a bit more.....perfect!" Or maybe the ball lights up like the studfinder and the ump moves it along until the light stays on.
