There's no reason for the media or anyone else to "attack" MacKinnon. He's not only consistently great during the regular season, but also playoffs.
Players deserve criticism when they don't perform to expectations. When they play well, they get credit for it even when the team loses, a good example is Morgan Rielly in the 2023 playoffs.
Marner sometimes gets criticized because historically he paces for 100 points for the first 86 games of the season, then his production goes down by more than 50% and to a lesser degree, same thing with Matthews. Mackinnon on the other hand simply does not falter in the playoffs. He has never been less than PPG in the playoffs, against Dallas he put up 11 points in 7 games, led his team in points (also +-) so only an idiot would "attack" him.
