I think we need to mix up his linemates, I don't like him with Perron and Amadio,
I'd try something like this, maybe swap Amadio and Perron
Perron-Norris-Batherson
Tkachuk-Stutzle-Amadio
Greig-Pinto-Giroux
Gregor/Cousins-Gaudette-MacEwen
I'd be more drastic and move one of Norris/Pinto to the wing. You could go:
Norris - Stützle - Batherson
Tkachuk - Pinto - Giroux
Amadio - Greig - Perron
Gregor - Gaudette - Cousins
Or
Giroux - Stützle - Batherson
Tkachuk - Norris - Pinto
Amadio - Greig - Perron
Gregor - Gaudette - Cousins
If we want to have success, we need to get more offense out of Greig and Pinto. Greig is a shell of himself at wing, especially his off wing, and Pinto is really struggling (can't win a faceoff either). He's played RW at international tournaments and looked good doing it.
And I like Amadio, but he's a bottom 6 player. He lobotomizes offense if he's on a line that we want to score.
