Schenn is going to be the No. 7, IMO. I think the battle for No. 8 will be between Juolevi and Hunt in particular, with Keeper having a shot as well. Hunt is a ridiculously popular guy among teammates and coaches, so it wouldn't surprise me if he edges out Juolevi for that last spot. All three of them (Juolevi, Hunt, Keeper) are waiver eligible if I'm not mistaken.
On the forward side, the battle for the 13th F will sure be interesting. Dowling has versatility as a guy who can play center, Di Giuseppe brings a really physical/in your face brand which would seem to directly compete with MacEwen (who is the guy I would keep, but seems to be in Green's doghouse), and then there's Highmore in that mix too. He had a good showing as the 2020 season wound down, but he'll be in tough with these guys for the spot. And lastly - does Nic Petan merit consideration as a skilled guy to slide in on scoring lines if someone gets hurt? He's a bonafide star at the AHL level, but more of a stop-gap solution in the bigs.
Lots of interesting moving parts heading into camp.
