Nope. Bad sportsmanship does not fix bad sportsmanship. Go out and shake hands. Then go out there and win the next game.
Trust me I am not defending the other coach but having someone do that could set off a coach who is clearly not an adult. I hope his parents talked to their kids and told them
that it's always the thing to do to shake the other teams hands. I also wonder about the coach who vows that he won't do it and that's why I wanted to know how the last runs were scored in order to get his level of adulthood.
