The reason why I asked is that typically the woes for entering the zone stem from him, and most of the zone control stems from him with very little positive result.
First thing I would do before moving anyone off is getting Marner and Rielly moving more on the PP. I'd also give Rielly more free rein to wheel by pushing our forwards down low as much as possible to open up space up high. Rielly does not have a cannon like a Hamilton or Weber but he can score with his shot and it is really nice for tips, which is perfect for a guy like Tavares in that hashmarks area.
We should start getting our points more involved on the PP. They are constantly active at ES and we are doing excellent at ES. Why not do the same thing on the PP?
Look at 3:06 in our last game's highlights. Rielly gets the puck high slot and it is nothing hard or fancy but it leads to at least 2 good chances in front where Holtby has to make good saves.
I think it is fine if the Leafs continue stacking the 1PP in the meantime (Rielly, Matthews, Marner, Tavares, and Nylander). I would do my experimenting with our 2PP. I'd try Dermott at the point instead of Muzzin (save Muzzin for more important minutes, and let Dermott get more involved in something he can do well) and then experiment with Robertson maybe? Thornton, Simmonds/Hyman, Galchenyuk, and Spezza seem to be the 2PP forwards right now. I don't think it would be too hard to give Robertson a chance in there once in a while.
Here is my issue with keeping everyone the same and changing the plays instead.
They already have the freedom to do this . In their current formation the coaches are open to them being creative. Its just not gonna happen because Rielly doesn't have the toolset for it on the PP. The puck does not move efficiently with Rielly in his current spot . When your PP relies on constant movement it has to move to the right as efficiently as it moves to the left. We dont have that kind of movement. Even the movement to the left isn't anything to brag about. Teams already give Rielly so much room and he doesn't do much with it.
For your idea to work maybe Rielly can move down low and matthews and marner take over points (Marner can get tip shots through and matthews has the bomb) but that just aligns with taking Rielly off period because a forward would be better for the down low role.
Rielly is good ES because things happen differently. Either in transition, off a rush, off a bounce etc etc. PP is systematic and structured. I really want your idea to work but Rielly isn't going to do it when it gets to that structured and high offensive IQ stage.
A good analogy is a NBA player that rains 3s all game but has a free throw percentage below 80%. The 3s are happening off catch and shoot or in the moment plays. Free throw is different. You're just standing there in one spot and have to drain a shot. It's a different craft than normal game play . Similarly, Rielly is good when things are happening in the moment on ES but falters hard when its time to lead a more crafted PP.
Yes the plays you suggest will happen at times but the frequency they occur will be very low if Rielly is your main guy at point.
I obviously hope I'm wrong because I am desperate for the PP to start working.
