Oooh, so you block the leg kicks. Hey guys, I think I can beat Aldo now, you're supposed to block!! Surprised he released such a top secret strategy.
Kidding aside, there are some awesome leg kickers in K-1 and muay thai. I don't know if Aldo's leg kicks will be able to catch Pettis, but I think everyone trains for them and no one has been able to stop them.
