Defending the house is key to the success of a hockey team. Preventing the
opposition from scoring goals requires a team effort. The defense needs
to contain the puck, put pressure on the puck carrier, and, ultimately, gain
possession of the puck. The defense wants to shrink the rink, forcing the
offense to send the puck to spots where it’s easy for the defense to pressure
the puck and difficult for the offense to take a shot. When the defense can
shrink the rink, it can get five defenders in the house, ready to make contact,
pressure the puck carrier, and regain control. Once the defensemen
have control of the puck, they can start a breakout to get the puck down
the ice and perhaps set up a goal.
