what does a power play do in hockey
Power play (sporting term) In ice hockey, a team is said to be on a power play when at least one opposing player is serving a penalty, and the team has a numerical advantage on the ice (whenever both teams have the same number of players on the ice, there is no power play). Up to two players per side may serve in the penalty box, giving a team up to a possible 5-on-3 power play. If a goaltender commits a foul, another player who was on the ice at the time of the penalty serves.[1]
Face-off A face-off is the method used to begin and restart play after goals in some sports using sticks, primarily ice hockey, bandy and lacrosse. The two teams line up in opposition to each other, and the opposing players attempt to gain control of the puck or ball after it is dropped or otherwise placed between their sticks by an official.
