As am I. I like Konecny for the same reasons you do, and I like the fact that he's someone that would most likely find a way to contribute in some capacity at ES in limited, 4th line minutes if that is what his role ended up being.
I thought that in 2010 and 2014 guys like Nash, Carter and Marleau really excelled at getting up and down their wing at speed, backchecking effectively, and using their size/strength advantage together with that speed to lock-down the other team's wingers. While none of those guys had really played defensive roles before, they excelled in defensive roles at the Olympics and had the obvious scoring ability to, along with Toews as their centre, really tilt the ice in favour of the Canadians. I would imagine their puck possession/corsi ratings would have been well north of 70%. That's why I really like Byfield as someone that can be deployed in a straight up-and-down winger role that is optimized for his size, strength and speed. He doesn't need to do anything fancy, just get up and down his wing quickly, eliminate the winger he's matched up against, and complement his centre in the o-zone.
What we won't have in 2025 or 2026 is a "big boy" line like we had in 2010 and 2014 with Getzlaf/Perry + Morrow/Benn. I liked how the Getzlaf lines were able to change the pace of play, slow things down, and play a heavy game in the corners and in front of the net. In terms of style of play we don't really have anyone like Getzlaf, though I think Johnston is a player that is quite crafty and skilled in-tight with a nice release, kind of like Perry (without Perry's physicality). Hyman is too. We just don't have an obvious trio of forwards that we can put together. That's why I kind of lean towards creating a team that amplifies our strengths, rather than one that attempts to conforms to a successful template from years past when we don't really have the horses to do so.
