A defensive strategy used in ice hockey by Western Conference teams to prevent an opposing team from proceeding through the neutral zone (the area between the blue lines) to force turnovers. Originally coined by CBC analysts, although this same tactic employed by Eastern Conference teams is known as The Trap.
The Canucks threw a defensive blanket over the Blackhawks and kept it there with a minimal number of breakdowns -- rarely venturing over their opponent's blue line.
