As I've watched the Indiana HS State Tourney each year since 1996, and the NCAA's each year since 2007, I've noticed an inordinate amount of left-handed finalists and champions. The population of lefty's is only like one in every ten, but when you watch high level wrestling, that proportion becomes much much higher, much closer to 50% of the finalists at both of these tourneys some years. Probably no way of gathering this data, but interesting observation nonetheless.
