Anton is still an enigma. He will play a LONG time in the NHL. He is a legit 6'5" and is not a blob on the ice- he skates pretty well. And as Teemu said, he has the best shot on the blackhawks since doug Wilson.
Here's the enigma part..... he is not real good positionally. He chases his guy too much, and in Camp would chase him all over the ice pratically. He has gotten better down in norfolk, and hopefully he'll continue to get better.
He is definately a high ceiling prospect. I don't think I'm bs'ng when I say that in 4-5 years he'll have a top 5 slapshot in the league on the point(its that good) and unlike guys like Sami Salo- he likes to shoot and looks for his shot.(salo of course has a cannon, but seems like he doesn't use it enough).
He has to get better positionally. He's nasty in front of the net and can be borderline dirty(which we like to see here let me tell ya). He has what it takes to be a stud in the NHL. *BUT* so did Boris Mironov- and he's a lump of poop.
He didn't play bad, against some real tough competition(Cal/St Louis/Col/Det). But was under 10:00/game of even str play- so we didn't get to see too much of him.
He will definately play next season with the hawks. He pretty much is pencilled in already. With his size, shot, and skating ability- he has a chance to be a top tier defencemen. That lack of hockey sense, along with a bit of a prima donna attitude means it is equally likely he's another Mironov.
Hope that helps... I've seen all of his NHL games, watched him in last years rookie camp, and this season's training camp. If you have any questions feel free to ask.
