I have seen both sides of bad/great sportsmanship. My son has wrestled a couple of the same kids for 5 years. One of them is on his facebook and they talk regularly. They scrap on saturday and leave it on the mat. My favorite picture of this year is of my son and another rival of his standing with their arms around eachothers shoulders, both bleeding and smiling after a tough match with eachother. It doesn't get any better than that. The good far out weighs the bad.
