Not to be a debbie downer, but that move isn't as difficult as it looks. I only played for 4yrs and had that "trick" mastered after 2 of them, although I was playing year round(ice and roller). Most of the really talented youngsters in the camp I used to coach could replicate that within 3 trys, although the scoring part probably wouldn't happen.
Coming from a hockey backround, its not that impressive, the same shot has been on the web for a long time. My best guess is he saw it and practiced it over and over till he made it everytime.
That was cool! The thing about it is he tried it just like Marek Malik tried someting different in the shootout that he was in!
