im a little confused
Okay. When the offensive team crosses the opposing team's blue line before the puck, that's called offsides. The puck must cross the blue line in advance of the offense. Sometimes, offsides can be delayed if the offsides player(s) returns to the neutral zone before the team legally re-enters the zone.
Does that help?
