Going into camp, this is the forward group I'd like to see take shape:
Jost - Strome - Raddysh
Steel - Barzal - Gauthier
Dubois - Roy - Stephens
Howden - McLeod - Senyshyn
Speers
The 1st and 2nd lines will be counted on to provide offense for this team. I like the Strome & Raddysh pairing for the reasons I've already mentioned, and I like Jost with them as a high-IQ, all-around offensive threat that should be able to play well off of Strome. Barzal & Gauthier played together last year, and while I'm not normally in favour of playmaking-biased forwards at wing, I think Steel fits well here with Barzal as the catalyst and Gauthier as the finisher.
3rd line is the matchup line. Two big fellas in Dubois and Roy, and some nice grit, speed, and experience (not to mention scoring ability) with Stephens. If Roy's skating becomes an issue, the simple switch would be to move Stephens to center but at this point I see Stephens as more adaptable to the wing.
The 4th line is really a third scoring line constructed around the elite skating ability of McLeod and Senyshyn. McLeod has strong puckhandling skills in the middle, and there is good finishing ability on the wing. Senyshyn in particular is heating up at the right time. With McLeod and Howden, this line should also be strong defensively.
Speers is a good all-around guy to have as a 13th forward, with the concern being his limited game action this year (only 4 games in total). If he can't get himself in game shape over the next two weeks, Cirelli or Joseph would also be options here.
