Pros are serious about new rules

Standing in the fourth fairway of PGA National after his ball had plugged in the turf, he squatted halfway down, reached behind his legs and pretended to take a drop in a motion that, when screen-shotted just right, could best be described as looking like someone doing No. 2 in the men’s room, the gallery getting a good laugh out of the mockery.

Whose idea was this new rule? Why not make it so that drop is from knee height to shoulder height.
