Because they put too much responsibility on Mackinnon’s stick on the PP. I actually completely agree with you. I would actually move Kadri to PP2, move Landy to the bumper, move Nate to Landys spot but have both Mikko and Nate rover from down low to the half wall/dot on their respective sides. I don’t think Mackinnon needs to be on the “point” on the PP. he scores more from the faceoff dot and as good as his shot is, it’s not Ovie/Laine. Plus this gives both Nate and Mikko more playmaking opportunities down low where they excel and then they can alternate back to the dot to get in shooting positions when needed.
I’m a dork so I drew a diagram but this is what I’d do (would also be fine with Girard over Byram)

When Nate goes low, Makar follows and takes over the half wall. Byram floats over to the middle. When Mikko goes low, Byram follows. It’s a constant rotation.
