I mean it's very hard to convince me a team could not benefit from a guy like Smith. I am not sure where you are getting your impressions about playoffs but by all accounts Smith has a ton of heart and tenacity in his game. He is willing to go to the tough areas and unafraid to pay the price. He's extremely quick and agile, has elite level hands, good shot, probably the 2nd best playmaker in the draft, kills penalties, etc... he does it all and does it better than most. And he's a center, good on the draw.
He has all the physical tools to make it to the NHL. I don't really see much risk in terms of his style being translatable to the NHL.
