Officiating two sports concurrently

If that was the case they would only use former pro players to umpire MLB games.

I'm not talking about levels of play, at least not too much. It isn't about what we do or how much the players understand what we do. Its more about knowing the game. A hoops official needs to know the difference between a man and zone defense, a single post and double post offense, a guard and a forward, etc. He doesn't necessarily need to know what a match-up zone is or how it compares to a basic zone.

A football official needs to know the difference between a guard and tackle, a safety and linebacker, what a screen pass is, etc. He doesn't necessarily need to know the difference between a cover 2 and the old strong/weak safety.
