Machida still struggles against his defensive Karate DNA. It's crystal clear. He already addressed he would be more aggresive in the future as he aknowledged ppls criticism, but he still fights back paddling as avoid confrontation is his martial art main philosophy.
It's amazing, though, he got the belt and keeps himself at elite level with so much restrains.
His first instinct of fighting was to not get hit. And he grew up under that idea. It is hard to change, especially when you still have that style as your base.
People said he would make Dan look old and slow. Which he sort of did. But he didn't clown him. He proved he was quicker and disciplined to do it for the whole fight. We all knew that.
