Potrias with Marchand is a great spot for him. I know he'll go against the tougher defense, but his vision is already better than Coyle. His quick passing and natural instincts are really going to open up that line. If they need to be more defense near the end of the game they can always shift Coyle back.
The only thing with him is can he handle the grind. Thats really tough on any rookie.. The rest of his game is NHL worthy and the thing that happens natural, strength, will happen. We got a good one.
