Roy should had played the whole season in Laval. Of course, injuries in MTL derailed the plan. But I still think he needs to prove more at AHL level, mainly consistency and involment. Struble should start at AHL level too. I would not rush Mailloux nor Reinbacher at NHL level.
Habs should start next season with these d-men and see from there who could be traded: Matheson, Guhle, Savard, Hutson, Xhekaj, Harris OR Barron and Kovacevic. Harris or Barron could be part of a package to pick earlier in one of the two first rounds.
Available affordable UFA forwards: Mantha, Duclair, Carrier, Stenlund, Duhaime. They can fill holes for a couple of seasons.
Should go: Dvorak, Ylonen, and maybe Anderson if they can find a dancing partner.
