Its hard to draw any firm conclusions on this practice roster. Fabbri on the right side is interesting (given he's a natural center, but a LHed shot), as is Petan on the McDavid's wing with Crouse (which could be good or bad for Petan depending on how you read it). The Gauthier line is probably modeled on the Getzlaf-Perry-Benn "big boy" line from the Olympics, but I believe Ritchie and Virtanen would compliment a center with a stronger offensive acumen much more than a defensive center like Gauthier, and in a lineup that may be a bit short on size, I'd lean towards spreading what size I do have around a bit more. Still, its probably worth a look at camp, it could be a good possession line.
The defense looks strong, I think there are really only two spots up for grabs between Morin, Sanheim, Bigras, Heatherington and Hicketts. Edge to the first two for now, perhaps.
