Stay-at-home defensemen are hockey players primarily focused on defensive responsibilities rather than offensive contributions. Their main role is to prevent opposing players from scoring by blocking shots, winning puck battles, and maintaining strong positioning in their own zone. They often excel in physical play and are reliable in one-on-one situations. These players typically have a strong understanding of the game and possess good skating and puck-handling skills. While they may not score many goals, their value lies in their ability to keep the puck out of the net and support their teammates, making them essential to a team's overall defensive strategy.
