I'm a huge fan of Yale's system. Puck pressure in all zones. No matter what line is on the ice, puck pressure. Quinnipiac's big guy lives behind the net, has a great game against SCSU because they basically give him the space below the goal line. Yale says screw that, and he isn't able to get comfortable down there because he's got a guy with him attacking his stick the entire time.
Give credit to both teams. Its not a zone to zone game. The pace is fantastic.
