slapshot........

The hockey player looks to my eye to be using what we'd call a Shoulder Throw .....
His active shoulder takes his bent trail arm close to the ice before he thrusts, bends the shaft along the fore and aft axis against the ice. Sticks bend in that direction far easier than they do in the other direction (top / bottom) given the rectangular design of the shaft when viewed in section. They were made that way.

The horizontal hinging fans will also like to point out the rolling club face er blade post impact. Cant shoot it 100 mph with vertical hinging. The closed face approach to impact is undone during the contact with the ice but releases . The puck leaves square to the blade but spins like a frisbee to make it fly. No backspin. Vertical has it place though....for a high flip shot etc .

I have this suspicion that one reason hockey players make good golfers is that they immediately get how the ball needs to be stuck with a closing face. Well that and the fact that girls love a guy in smart golf attire.
