Mr. Church,
Don't know for sure, but I had heard that teams in Oklahoma don't shake hands. Now, back in the day when I was competing in high school, our team didn't shake hands with opposing schools either. However, when I was a freshman I was told that a few years earlier an opposing coach had shaken the hand of one of our wrestlers (the coach's son) and had called him a racial slur because they had lost. Since that year, our coach decided not to shake hands with other coaches either. And we all know, or should know, you do what you're asked by a coach without question. Maybe the last statement is to "old school" for some of the youngsters to understand.
