This is just a thought on the travel violations. I had many dicussions with fellow officials regarding this topic. I was calling it when it wasn't a travel, not calling it when it was, etc. I began to videotape my games on the advice of a veteran official. I was able to see a whole different game. Not only did I improve on the ability to recognize violations/fouls, but I also saw how goofy I looked doing certain things. I now make it a practice to video a minimum of 4 games per season. It has been a tremendous aide in improving my contribution to this game.
This might help others as it has helped me.
