The 2-1-2 is an aggressive-style forechecking system designed to place pressure on the puck carrier. Its name comes from the pressure-style being used where the first two players aggressively pursue the puck, one player stays slightly higher for middle support, and the defense hold their regular positions on the blue line.
The Box Plus One hockey defensive zone coverage system is designed to minimize the scoring chances from within the prime scoring areas.
