I once had a coach tell me that you should wrestle hard enough that you do your part to ensure that the referee's decision's won't decide the match. He said that you should go into the match already figuring the reff might screw you out of two points so do what you can to make the match not come down to that two points. Referee's are human and humans aren't perfect. Just remember that next time you cuss a reff because they are trying their best out there.
