Too lazy to find it, but Crosby did that already. The kid copied him. I don't know if it was in an actual shootout or just a promo vid or something, but I know I've seen Sid do it. Maybe on a Gatorade commercial or something lol...
Personally, I think that stuff is ok at the all-star game/skills comp (as in the vid), but I think a lot of die-hard NHL players/commentators look down on that hot-dog, Mighty Ducks Disney type shit if/when players try it in real games.
