If Andrew Shaw were a soccer player, his headed goal Tuesday night in an extra period would not have been unusual. It also would have counted.
But, alas, Shaw is a hockey player for the Chicago Blackhawks, and hockey players are not allowed to use their heads — or any other part of their body, at least not intentionally — to knock pucks into the net.
Still, Shaw created one of the most memorable moments in the N.H.L. playoffs so far. The Blackhawks were on the power play 8 minutes 47 seconds into the second overtime in Game 2 of the Western Conference finals against the Anaheim Ducks when Shaw leapt for a high floating puck and knocked it in with his head.
