I know for a fact how much umpires make and it is way too much. It is also going up next year and the year after. An online test, thats funny, its easy to pass a test when you have the book to use.
As a comparison? How can you compare teenage boys with men in there 20's, 30's, 40's etc? Also, teenage boys do not get paid to play. Umpires get paid to do a job, and in most cases, umpires do a great job. However, there are exceptions.
About screw-ups. Your right they are relative, but that doesn't make them ok. Missing an occasional ball or strike is one thing, but a pivotal play in the game is another.
I believe that "many" umps have to much pride. To say a coach is showing you up if they show you the rule book is stupid. If your wrong, then your wrong. You should swallow your pride and admit it.
I understand that umps are human and make mistakes. Players and coaches make mistakes, but let the actions of the players and coaches dictate the game. A call by an umpire SHOULD NOT DICATATE THE GAME!!! I'm not talking about balls and strikes. I'm talking about rule calls.
Calls should not be determined by the umpires attitude towards a certain coach or player. A strike zone should not widen because a batter gives the umpire a funny look. The strike zone should not shrink when a pitcher shows emotion that he did not get a call. Furthermore, a play at the bag or at the plate should not be determined by whether or not the umpire likes the coaches or players. To me, its a power trip when they do that. Its a "because I said so" mentality that gives some umpires a bad rep.
Don't you tell me this doesn't happen because if you do your full of crap. I know umpires do things like this. I've heard them admit it.
