The referees have no accountability what so ever. Coaches aren't allowed to grade them and if they want to come in and do a bad job one night or take out their emotions or feelings on a team there is nothing the coach can do except blackball them afterwards. You have too many people doing it that are not going to get better or try and learn, they just want the easy cash, and that's what it is. Tell me a profession where a person can make $30 an hour with absolutely no clue what they are doing.
The other problem is referees wanting to be seen. You get some officials who blow their whistle to be seen. They feel like everyone is there to see them blow their whistle. Watched with my own eyes a referee other night big time the entire game. Every out of bounds, block/charge, and jump ball situation he would blow whistle and wait couple seconds then make his call like he was Hulk Hogan playing to the crowd. Here is the deal, the fans didn't come to see you and if you are a really good official no one will never know you were there because you just called the game. Until there is accountability for them, it is pointless. If someone has a job and stinks at it they get fired or put on improvement plans. These guys have no one to hold them accountable at all.
