Babcock did not use Pulkkinen properly this year when he was up. He mainly put him with bottom 6, low offensive skill grinders. He should have been playing with Datsyuk or Zetterberg who would know how to put him in position to utilize his shot. If they put Pulky on a line with skill players I def believe he has 25-30 goal potential.
The recent Blashill interview explained all the reasons why Pulkkinen hasn't broken through yet. It boils down to the usual things, namely consistency in defensive play without the puck. He gets ice time in AHL because he scores so many goals, not because he's a well-rounded player. Babcock would have built the scoring line around him if he scored as many goals in NHL as he did in AHL this season, and I think he was kept up as long as there was the tiniest chance of that happening. Blashill said that he can forgive other shortcomings because Pulkkinen produces so much scoring -- But in the NHL he's not doing that. It's something that Pulks has been working on and he has become much better at playing 200' consistently, but he's not there yet.
I agree that his potential is pretty awe-inspiring. If he can translate his game to NHL and have a similarly dominant position as in every other league he's played in, it would mean scoring goals like Ovechkin. The YT highlight compilations give the impression of a modern day Brett Hull. It's a tall order but I think it's not impossible with the shot he has. Suppose he doesn't quite get there, 25-30 goals per season is a reasonable compromise.
I think players like that who are used to becoming key players work their butts off until they get there.
