He leads the league in PP goals and the PP has gone up 3% since last season. He must be doing something right. Specifically, helping to gain the zone, facilitate east west movement at the point, and get shots on net.
I assume you want ghost in his spot. Ghost flubbed a puck coming out of the zone yesterday. It happens, as it does with Provorov. I don't think Provorov is bad at it. He uses both sides of the ice, something they obviously want this year. Maybe Ghost can do that, I don't know. He wasn't asked to before.
What I do know is this is a very different PP than years past. At it's height, it was a half ice PP with 2 shooting options, a point shot (Ghost) and a high slot (Schenn) option, and a strong net front presence in Simmonds. After losing Schenn, it took a hit as they tried to replace that high slot shot, then as simmonds declined it took another hit. Ghost, in that scenario was asked to play catch with Giroux and hammer home shots. It worked because he got the shots on net and could drive when a lane presented itself.
Now, they clearly want to use the whole ice, and don't have as strong a net front presence. Ghost hasn't been as accurate (could have been the knee, but I can only go off what we know) and was never asked to distribute to his right consistently. The PP has improved from last year with Provorov, and he clearly has the coaches trust. He is absolutely good enough and the results speak for themselves.
