Defending in hockey is fundamentally about positioning—being in the right place before you need to make a play. The geometry of defense determines success more than raw athleticism.
Gap Control: The distance between a defender and an attacking player is called the gap. Too much gap allows attackers to build speed and make moves; too little gap allows them to blow past. Finding the optimal gap is the foundation of defensive positioning.
Angling: Rather than chasing attackers directly, effective defenders take angles that cut off skating lanes and force attackers to the outside. Angling uses the boards as an extra defender.
Defensive Side Positioning: Staying between your opponent and the net—goal-side positioning—ensures that even if beaten, you can still recover. This principle applies whether playing forward or defense.
Net-Front Presence: The area directly in front of the net is the most dangerous scoring zone. Positioning to clear this area and box out attackers prevents high-percentage chances.
