I got a lesson in Sportsmanship from a buddy of mine. He's a big BSU fan and an occasional BYU fan. Occasional meaning that he cheers for BYU if they aren't playing BSU.
He went to the BSU game in Pullman this last weekend vs WSU. He took my son to the game since he is friends with his son. Before they went to the game he told the boys that each of them had to seek out a WSU fan and thank them for their hospitality and compliment them on their venue. Further, he told them that they had to do it 3 times, once before the game, once during, and once after, regardless of outcome. The boys did as instructed. (these are 17yo boys). My friend says that he does this at every game, home or away. His opinion is that it fosters good will and shows good sportsmanship.
Personally I think 3 times is a bit overkill, but I'm grateful for the lesson that was taught to my son. He had positive interactions with each person he spoke with. Not sure what the 3rd interaction would have been like if BSU had won though. Nonetheless, a good life lesson taught.
I think that I am a good fan and I usually have positive interactions with opposing fans when they are near me but I certainly don't seek them out. While I'm not going to set a number for interactions like my friend does, I do think that I will make it a point to be more welcoming and engaging to opposing fans at games, whether home or away. I think we have an awesome fan base but we can always be more welcoming and engaging with the opposing fan base.
