Interesting logic here. It's still good to realize that Granlund and Teräväinen had also some quite weak aspects in their game compared to Laine, Pulju and Aho. They both were (and still are) especially lacking fast skating, strength in their shot and their body, and their defensive play was at best mediocre. Sure they both have excellent hockey IQ, great stickhandlng and passing skills, but they still had quite glaring weaknesses, especially for playing successfully in the NHL. Laine, Pulju and even Aho are much more balanced players who don't have so big and obvious weaknesses. And their strengths also compliment more the style of hockey that is played in the NHL.
I admit that I'm still a bit disappointed in Granlund not adjusting better to playing in the NHL. But after all when thinking more of his weaknesses, my expectations on him were a bit high after all. With Teräväinen I have been after all positively surprised. He has already adjusted much better and quicker than I expected. He is that weak physically and his skating (especially speed) is so average that I thought it would take him much longer to be an NHL regular.
