It's amazing seeing Kempe do well in these series year after year, but I got thinking recently that it seems to be a thing early in a series and eventually the tide turns on him, so I dug into it for fun.
In Games 1 or 2 over the four years, he has 8 goals, 7 assists and 15 points and is +1 in just 8 games. In the other 14 games, he's 7 goals, 6 assists and 13 points and is a -15 overall but over 14 total games.
5 of his 8 multi point games have been in Game 1 or 2s. His only other three was a great 3 point overtime win in Game 5 of 2022 which was kind of his breakout playoff game, a 2 point night in a 6-3 loss Game 3 of 2023, and a 2 point night in a 7-4 loss on Friday.
