Eh, I'm not too sure about this.
I watched 8 of his 10 WC games and would literally just stare at him when he was on the ice, with our without the puck (as long as he was in TV view), and he needs quite a bit of work defensively...as do most 18 year old players. If I had to find one thing he really needs work on it's his defensive play. While he does backcheck, he is very lost at times when play is already in his zone and losing view of his man on a regular basis. He also doesn't really move much from the point man (which yes is his man but sometimes you have know when to be a little aggressive and come off that point to help a bit by the dots).
Like I said, he's 18, and it's not really a knock, but he is far from perfect defensively and I definitely wouldn't consider it at this point one of his good attributes. He will learn.
And yes, it was a small sample size but that's what I gathered from it.
I think you misunderstood his post. I thought he meant that Kakko's linemates should have those attributes.
