Regarding Nylander, Ehlers and Larkin:
I think people get a bit carried away trying to win arguments right now. I think all three always projected very similar, and all are on course as well.
Larkin in my book is looking just like I expected him to. As a prospect everything about him screamed fast-tracking and NHL-ready, and I'm not surprised that he's had an impact. My view on him long-term hasn't changed.
Nylander doesn't have the same "can handle every aspect of an NHL game"-feel that Larkin has, so he is molded in the AHL right now. He's doing everything there that you'd expect of a top center prospect playing in AHL, so I see no need to change my view on his long-term impact either.
The one where I've had to change opinion slightly is Ehlers. I thought he'd need another year to get stronger, but his slipperiness seem to make him effective enough as is. He's both answered some question marked and progressed faster than I thought.
I used to have Nylander as the strongest of the three, right now I'd probably have it reverse. Still, I think that long-term they are just incredibly close. Ehlers might have the edge in ability, but the other two might be more valuable due to position.
He'd be doing better than Larkin especially playing on Zetterberg's wing. Nylander and Zetterberg have a perfect European style of game that would mesh well. Larkin's on-ice shooting pct is abnormally high, considering the Red Wings are one of the lowest teams in shots on goal. He's overachieving right now. It's nothing to be cocky about, he'll come back down to Earth.
Larkin might be overachieving production-wise, but he is playing really well and from everything I've seen he meshes perfectly with Zetterberg. I see no reason to say that Nylander would do it better.
