That's the same video I linked. He makes contact with the board, yes, but he basically just lands on Rittenhouse. It's not like the After going frame by frame, on the youtube version, though, Hubor does pull his arm back slightly, so I'm no longer as confident that there's absolutely no wind-up.
there is a picture about halfway down this page that makes it look like he is really nailing kyle with the board. it looks brutal, right on his neck. -- but when I watch the video it goes so fast that it could also just be him basically running into him. So.. idk
