However it must be noted that this wasn't a points karate match. Accumulated damage must play a part. Machida's legs were purple at the end of the fight. And if he truly thinks that leg kicks can't stop a fight, maybe he should think about Pat Barry vs. Dan Evensen, Pedro Rizzo vs. Dan Severn...
I do agree that the leg kick is severely overrated. It didn't start doing damage and hindering Lyoto until the end of the fight. He was walking right through them, at first. I think they look so cool because Joe Rogan blows his load every time one lands.
