I think that's the crazy thing about Hasek is when you just look at him it looks like he's just flopping around out there, just going with whatever comes into his head at the moment. But if you really analyze what he's doing for every action there is a specific reaction he does. If a right handed shooter fakes right and goes backhand left, he lunges out with his blocker, stick flat on the ice, rolls over his glove hand sideways, he's no longer trying to catch the puck in his glove. He's trying to use it as another blocker. He then brings both arms out flat on the ice, head tilted back to see the play and both feet come up. He's used it on virtually every single righty that dekes left on him in his career. He knows that when you're on your backhand you have two options you can either go low, which he has taken away, or you can go high. The hope is that you go high because that's where he is baiting you to go. Now he his looking right at your blade flat on the ice, both feet in the air and all he has to do is guess based on your stick position where you will go.
I've seen some deep dives into the things he does and just like with profly, there is a save for every situation. He just did it in a far more athletic way, by flipping upside down. Now his arms are the butterfly and his pads become the chest. The genius is that he can stack them and take away a sizeable portion or he can split them, something your chest can't do. He also almost always tosses his stick when flipping over, usually throwing it into the net or letting it go towards the shooter.
