The idea that the president's trophy is a curse is absurd, people who view it that way are people who struggle to interpret odds and probability. The winner of the president's trophy has one the cup roughly 22% of the time but there are 16 teams that make the playoffs.
If you look at the other 15 playoff positions I guarantee none of those 15 by themselves win the cup 22% of the time. You do not have better odds by finishing in any of the other 15 playoff positions, and historically the top team has won more often than any one of the other 15 possible playoff spots.
Here is a perfect example of what you see when you actually look beyond the silly curse narrative that some media and fans cling to and do a deep dive into the numbers.
"Jonathan Weiss, writing for the Bleacher Report in 2010, also noted that of the teams between 1982 and 2009 that led the League in points during the regular season, 12 of them (45 per cent) reached the Cup Finals, while of the other 405 teams during that same time period, only 42 (10 per cent) advanced to the final round, concluding that "the team that leads the NHL in regular season points is four to five times more likely than any other team in the playoffs to make it into the Stanley Cup finals, and seven to eight times more likely to win the Cup""
