Here is Washington Capitals defenseman John Carlson dumping the puck into the Penguins zone and using the boards to fake out Penguins goalie Tomas Vokoun four minutes into the second period. Carlson successfully got Vokoun to anticipate where the puck should have been and banked the puck into a wide open net for a game-tying goal thanks to a friendly bounce off the board partitions.
As Pierre McGuire noted, a similar bounce almost slipped past Vokoun earlier in the game, so he should have been aware of the Capitals sneakily exploiting the new, player-safe boards. All is not lost, however, as of posting, the Penguins lead 5-3 with 13:00 left in the third period. Still, John Carlson is a magician.
