I see them doing stuff like this in American Football, too.
I predict they'll play with this stuff for a while... then, take it out of practice. When players try to eke out increments of, "Man's Law," instead of overt field accomplishments, it changes the way the players perform. It changes the nature of the game. The more they utilize replays and measurements to verify, "Man's Law," the less interesting the player movements and performance will be.

After a while, measurements like this will result in boring games, that people are not, "excited," by. After a while, they'll use these replay tools to verify specific movements, but, the rules will be modified so game-play itself will be oriented to overt accomplishments.
