Centre is much more about size and speed than it is about playmaking nowadays imo. Centres skate more than anyone, they have the most defensive responsibilities, and then obviously faceoffs are crucial as they drive possession. That’s why Norris and Pinto (and Ostapchuk) are centres.
I don’t think Greig will play as a C on this team. The trick here is for Ottawa to find a playmaking winger in the top 6 - whether it’s Norris or Pinto there, it’s not their strong suit, but that doesn’t mean they can’t be in that position. Marner is more the playmaker than Matthews, Kucherov more than Point etc - obviously extreme examples here, but the lines just have to be constructed accordingly.
The problem Staios has is that he has 3 third line centers and he'll be paying them a combined 14.95M next year.
Norris has an elite skill - his shot. The problem is that he can't create opportunities for himself or for any of his teammates.
Your examples of Matthews and Point don't really apply. They're elite scorers who can create their own shot. Yes, they also benefit from playing from great players, but if you removed those linemates, they'd still find a way to score their fair share of goals and generate chances.
Norris can't do that. He's entirely dependant on someone else creating opportunities for him. If that doesn't happen, he's an offensive black hole at 5v5.
We have two options with him if he remains on the roster:
1. Keep him at C but accept that he's going to produce nothing for you at 5v5, so transition him into being an $8M checker who plays PP.
2. Try turning him into a trigger man on the wing who can ride shotgun with Stützle.
It's time to try #2. His advanced metrics at C this season are absolutely putrid, and they match the eye test.
Greig is better suited to be the #3 (and he'll be paid like it), and Pinto is better suited to be the #2. We need Norris to become a top line winger (i.e. 35-40 goals).
