You can’t really dunk on your opponents in hockey, but Sidney Crosby got about as close as you can when he pinged a shot off of Antti Niemi’s shoulder from a tight angle, waited for it to rebound back to him, picked it out of the air, and bonked the puck in off of Niemi’s back.
The Penguins were tied until Crosby scored this one, but they went on to win by four goals.
