As to the Missouri wrestlers not shaking hands with the opposing coaches, that is something that we as a State do not do in Missouri. They have been conditioned not to shake hands after individual matches. How many times do you need to shake the opposition's hand. Once before the dual starts during warmups, once after the individual dual match, and finally after the entire dual has been completed. Missouri figured that it all the hand shaking wasn't necessary. In a dual, we shake hands with coaches after the entire dual is over. In tournaments, we shake hands with opposing coaches sometime during the day. Its not required. If you feel that you must shake hands with an opposing coach, you look for a more opportune time than right after a match when the coach is trying to either get another wrestler ready for his match, console a losing wrestler, or critiqueing winning wrestler.
