Looking at some of the lines from the CIS games at least to start with, particularly the 2nd one and then the cuts made after...looks to me like there's at least some framework for what they're thinking about doing starting to take shape there...
Crouse-Strome-Marner ---> looks to be what they want to go with, makes sense as Crouse would bring some real size and physicality to that line.
xxx-Barzal-xxx ---> both linemates from the 2nd game cut right after...placeholders for a pair of guys who weren't playing perhaps (Virtanen, Point)?
Perlini-Beauvillier-Gauthier ---> juggled a bit, but seemed to have some chemistry as a line, would be a solid 3rd scoring line if the chemistry works.
xxx-Stephens-Konecny ---> makes tons of sense as the foundation of a good gritty two-way checking line that Canada likes to take to these things...one that can also skate and chip in offensively as well. One of most likely Chartier or Quenneville would plug right in there perfectly.
Hawryluk as an "extra" who can kind of plug in anywhere, like Point last year would make sense. Good versatility. Or perhaps a guy like Merkley who has proven chemistry with Chartier and could be insurance for the younger guy Gauthier?
Putting it all together would leave:
Crouse-Strome-Marner
Virtanen-Barzal-Point
Perlini-Beauvillier-Gauthier
Chartier-Stephens-Konecny
*Hawryluk or
Quenneville?
I actually quite like that personally. Looks pretty good to me, given what's there. Spreads the size and speed over three "balanced" scoring lines...and then what should be a great "checking line" that won't make people groan...still plenty of ability to chip in offensively.
Can't really make heads or tails of anything with the blueline though.
