My worry is The Line He has centered has had the Team Worse xGF on 5v5 in all three games and this was with Okposo as His Winger.
I would have Him play in Rochester on Wednesday, Buffalo Thursday and then travel with the Amerks to play Syracuse on Sunday. I believe game experience would be of the greatest benefit to him now.
I imagine the Sabres will have a lighter practice schedule over the next nine days.
This being said, they have been developing Cozens correctly so I will yield to the Teams Better Judgement on Krebs
