IMO, Fagemo isn't really great in the top-six role, shooter's mentality be damned. At the NHL level, he doesn't have a lot of fantastic abilities where he'd be lethal on a regular basis. He doesn't have separation speed or strong puck protection skills to carry a line. He doesn't engage in board battles regularly or have vision with his passes to elevate his linemates. He doesn't shut down the opposition, either through tying them up or effectively blocking passing lanes.
I just don't think, aside from his shot, that he's really grown his game.
Can he improve? Of course. But it's in a way where he'd need to be carried. Byfield would try to set him up a lot and do heavy work. Fiala has the creativity to protect the puck and find him (when he's not doing a no-look pass).
Aside from those two, I just don't see a good fit that can complement his skillset and style to set him up for success.
