Watching Tampa these past few weeks has convinced me of two things:
1. Point needs to be in the top 6 on this team, playing alongside either McDavid or MacKinnon. With his finishing ability, motor, and defensive play, I'd think he'd look particularly good alongside McDavid, and would also provide that line with a RHS faceoff option...even though neither McDavid nor Point are all that great at winning faceoffs.
2. Stamkos should, at the very most, have a limited role on this team - as a triggerman on one of the PP units (he still has one of the best one-timers in the NHL), and defensive zone faceoffs from the right side. At this point there are better options at the wing position in the top 9, but I can see him rotate through on the 4th line or in an extra forward role.
This is how I would draw it up right now:
Huberdeau - McDavid - Point
O'Reilly - MacKinnon - Barzal
Marchand - Crosby - Bergeron
xxxx - Scheifele - Stone
Couturier, xxxx
Penciling-in the Crosby line, at least to start, should be a no-brainer. The MacKinnon line has a nice defensive element and elite LHS faceoff capability with O'Reilly, and Barzal has the speed and offensive skillset to complement MacKinnon. MacKinnon and O'Reilly also have familiarity playing with each other internationally.
The 4th line LW could be any number of players...Stamkos himself (he'd be playing his off-wing, which I believe he's done in the past and should be capable of), Couturier (if he somehow proves he can move to the wing), or maybe someone like Horvat that can bring a physical element to that line. It also wouldn't surprise me if Armstrong went with a more experienced, low-risk option like Tavares or Benn in that role, if the point of the 4th line is to grind down the opposition in their zone in limited minutes. However, I think there will somewhat of a youth movement in 2022 so my money would be on Horvat over Benn, Tavares, etc. Marner of course merits consideration for the 14-man forward group, but we're very deep at RW/RHS centers and I'd prefer to run with Point, Barzal, Bergeron and Stone at this point. And I think Suzuki (RHS center) will get serious consideration for a depth role as well.
