If players and coaches didn't lie and cheat there would be no need for umpires.



I think that's a chicken/egg problem.

A most of us know from our youth, pickup games don't have umpires and they work out OK. Adding an official transfers the responsibility.

As a Basketball player, I found that games with officials were rougher than games without officials because the foul call was then treated as "not my job" by the players.
