A soft perimeter winger is not what the Flames need in my view. Watching him he seems to excel when given space, struggle when pressured and hit. I think he will find the NHL has a lot less space than junior and he could have an problem adjusting to that more than what I have seen from the other guys.
As for a fit. Matthews and the Finns are better players so pretty clear why they are a better fit. For me Dubois is an obvious better player overall with the flexibility to play center.
Chychrun is a better player as well and as for fit gives us a lot of flexibility to either have a stacked top 4 with a cheap guy on a ELC which we could use with the salaries of the top 3 or the ability to move a Giordano or Hamilton to get the top 6 (or in that case top line) winger that we need.
Tkachuk is the power forward winger that we are lacking in our top 6. Gauthier has the size and scoring to fit well with Gaudreau and Monahan on the top line.
Personally I think Tkachuk has the biggest bust potential in that top 10 as his stats are so heavily inflated playing with Marner and Dvorak. Gauthiers game also has tremendous holes in it, despite the obvious toolset.
The reports out of the playoffs between Valor and the Armada is that he had a very pedestrian playoffs and probably needs quite a bit to round out his game.
I would take Gauthier ahead of Tkachuk but I'd take Nylander before either of them.
Hes got great all around skilled, not that soft (unless you put soft guys on the PK), and has good underlying stats and had a very impressive WJC where he elevated his game. Ok size, but won't be mistake for a bruiser certainly, but hockey IQ and speed are a plus in my books here.
Dubois is ahead of both of them. I'm still not certain Chychrun at this point but strong playoffs stats sofar.
