He very well could be. You are bang on about his edge-work and creativity.
It is just a matter of making it through camp and solidifying himself a spot in the top 6 on a line with Barkov or Trocheck.
Tallon has said he sees him playing on the 2nd line with Trocheck. Others have said he could push Barkov and Huberdeau towards their true potential and be their playmaker (while others see Vrbata skating alongside them).
If he does stick and transitions well...
I could see ~45-50 points this season (Teravainen/Eberle type season; replacing Jagr's numbers with potential for further growth in coming seasons).
Optimistic: 55-60 points (Zuccarello/Schwartz type season)...
Or he could just as well start hot (or cold) and fizzle out at around 30-40 points (Konecny/Jarnkrok type season).
Just a question of whether or not he can figure things out over here. If he does, I believe he has potential for much more heading into his second and third seasons. I do think he will be more of a Zuccarello type (speedy, undersized, playmaker = assist heavy) player but don't mind the Aho comparison either...
