I was going to take screenshots but SN doesn't let you do that with their streams.
If you watch the PP today though, I think you see a lot of trends that have persisted for a while.
1) Not being in scoring spots. Matthews touched the puck 2 times in the zone. One time he was along the boards and the other time he was in open space but was at the blueline. Tavares had pretty much the only great opportunity in that PP, and he made himself open in the bumper spot to get that goal.
2) We are constantly along the boards, and constantly move to the boards like it is some kind of magnet.
3) We don't move our feet away from the puck or even when we get the puck. Rielly was the only one to wheel within the zone on that entire 4 minute PP. Everyone else wouldn't take more than a stride or two before they look for a pass to an open area, which was often not dangerous. Guys get to their positions and won't move at all as the PK is pressuring.
4) We don't move the puck fast enough, which is often because of 2 and 3.
Look at these clips from earlier in the season when we were red hot:

Same personnel: Matthews, Rielly, Marner, Tavares, Hyman, etc. Matthews is in a spot to score, guys are moving around with and without the puck to get open, and not just waiting for the puck to come to them. They are along the boards but they are looking to make quick plays before they get swarmed.
So this is what I think we need to do:
1) Push Marner and Matthews down to the hashmarks and let Rielly be the man at the point so we are running a proper 1-3-1 rather than whatever janky 1-1-3 crap we are running right now. Marner and Matthews both are hanging around the blueline way too much and pretty much the only option Rielly has is to wheel down low, shoot towards traffic, or pass to them in a spot where they are not dangerous and the PKers can easily just swarm them, especially when they are along the boards. Rielly is on PP1 because he is a strong facilitator and an excellent puck mover, but you have to give him something to pass to.
2) Get the net front guy to move. If the flanks do not have a clear shot, get to the goal line and open up another lane beside the net. Simmonds has scored 2 PP goals because he was able to get the puck and roof it in tight:

We had guys in this similar situation waiting for a guy in Marner's spot to pass it to them right in front of the net. If Simmonds did that above, Marner would have to get it through the guy's feet. Instead, Simmonds recognizes that Marner is not getting that puck on or towards the net, gives him a different option, and he has enough time and space to roof it in the net.
Here is another segment about what is going well with the PP earlier on. Once again, we are not seeing that very much anymore.
