When you get every muscle in your body involved in a match--plus all of your mental capabilities--it's easy to lose perspective on what calls were right and what calls were wrong. And once a kid is emotional he is rarely objective obout what comes next. No ref is perfect--but his/her bad calls tend to go both ways. You may get screwed on one call and have a tough time letting it go---but hardly remember the favorable call he gave you at a different point in the match. I just don't know many really good wrestlers who blame refs for losing....that's part of what makes them really good.
