Hello everyone, From the book by Wayne Gretzky about ice hockey: "A smart passing team should be able to control the puck around the perimeter almost indefinitely, and an attacker coming in with speed has all kinds of room to step around a defenseman to the outside. North Americans find the adjustment to playing defense on the big ice a huge obstacle, and even some incredibly skilled Europeans never get the hang of the North American game. With less ice to defend, NHL defensemen learn to step up at the blue line, which can be a pretty unpleasant welcome to the North American game to a player who thinks he has room on the outside." Does "step up at the blue line" mean play more agressively at the blue line? Thank you.
