Freestyle is different than freestyle also. FILA changes the rules every few years, so much so, that the sport doesn't even resemble the sport that I wrestled in. Push out rule? Clinch? 3, 2 minute periods? What is this sport that they're passing off as freestyle wrestling???
And FYI, just about every single American folkstyle wrestler that competes in MMA has a freestyle back ground. Many have a greco background as well.
