I don't think poorly called games is limited to Tennessee only, however, I feel that there are just as many well called games that are never mentioned. Keep in mind that, as a general rule, your refs are not making bad calls intentionally. Refs don't really enjoy being heckled, ridiculed, booed, or insulted; therefore, they would rather make a good call than a bad one. Also, unless the ref is using his position to take a little power trip, which does happen occasionaly, he's not going to be out there throwing cards and making unfounded calls. Give the guys a break. They're performing their job to the best of their ability, just as the players are.
Most importantly, never, never, never argue with the ref on the field. It makes you, your coach, and your team look bad, and the ref is not going to change his call. Chances are, the ref will remember you next time, and then...well, you know what can happen. It's a lose-lose situation.
