Compared to other major professional sports leagues, playoff upsets are relatively common in the NHL. According to NHL broadcaster Darren Eliot, this is because the style of competition in the playoffs is different from the regular season: instead of playing different teams every night, the goal is to advance through four best-of-seven playoff series. The Presidents' Trophy winner may have to go through other playoff clubs who might have a hotter goaltender, a better defensive team, or other players that pose matchup problems. If the regular season champion's primary success was only outscoring others, they may be out of luck facing goaltenders that can shut them out. For the first time, during the 2019 Stanley Cup playoffs, all division winners were eliminated in the first round, which also saw the first instance that a Presidents' Trophy winner was swept 4–0 in the opening round.
