Refs making Bets, what's Next?

I have been to and watched many professional games, and after it was over, wondering if the refs had anything to do with the victory. You see it see it so often, one ref makes any iffy call, and then the next play you see what us fans call "a make up call". Do refs have more on the line then just their reputation as professionals who monitor and control the game. As you have heard recently on the TV and and read in the papers, an NBA official Tim Donaghy was convicted of betting on games which is a big no no, and even bigger, he was betting on on some of the games he was refereeing. Also to add to his resume', he has been involved in a couple off court verbal conflicts with NBA players, one including Rasheed Wallace. I actually witnessed this fight that you still hear so much about on the news. I was a ball boy at the time taking bags to the visitors bus, and on the way back I was actually caught right in the middle of the famous conflict. When the people who monitor the game have their own personal agendas that take over their job, when the people who are suppose to set the example break it so willingly, that is when the sport loses its thrill. Tim Donaghy used and abused all he had, when he had so much. He should be brought down quick, and this problem needs to be addressed more seriously, so professional sports don't lose their professionalism.
