Smith takes the draw then typically plays the winger role. Which is fine, that's the NTDP and they have their own way of doing things. So he's not really a center in the same context. And it's frankly hard to imagine an NHL coach on a winning team putting Smith at center. He's not alive until the puck is on his stick.
Carlsson was eased into the SHL on the wing, in the same way Elias Pettersson and every other forward was when they were 17 or 18 years old. The remarkable thing was when Carlsson was selected to play center on the Men's World Championship team, that is really rare.
