The start of the NHL playoffs included more penalties called than any other first round in almost a decade. Referees even whistled more per game than the regular season. The first week also featured more blowouts than one-goal games and a scarcity of comebacks. The second round should look more like old-school traditional playoff hockey after the end of the first began to show signs of change. Given a lack of upsets, the eight teams are left vying for the Stanley Cup with some of the league’s best. That also should ratchet up the quality of play.
