I am a little shocked by the harsh criticism on Kostin. Here are some things to remember. He is playing in a new country, on smaller ice, a NA style and he is an 18 year old playing in a men's league the AHL.
Also he is coming off missing an entire year due to a shoulder injury.
Due to those factors I was prepared to give him a little bit of a break his first year. I have always thought he was going to be a 2-3yr prospect before cracking the NHL. If he is still having issues around this time next year I will start getting concerned.
Essentially this.
I never really understood when people say they've been underwhelmed by him because I'm not really sure what they were expecting. How many 18 - 19 years olds play in the AHL period? How many play professionally after suffering from extensive surgeries? How many can still release the puck like Tarasenko after suffering from said surgeries? I'm fine with giving criticisms to players because no one's perfect, but the severity against Kostin seems higher than the others.
Honestly, I was in the boat to avoid Kostin when the Blues had a 2nd first rounder. I thought that there wasn't much chance Kostin could develop into a top-6 or top-9 player after all the drama surrounding his draft year and his seemingly lack of intelligence. But he looks much better than I thought he ever could. One, because I was wrong on the intelligence part, but two, his tools look incredible. His overall shot is, I'd argue, the best in the prospect pool. He makes good use on his size and balance by playing tenaciously against the boards and in open ice. His skating isn't his strongest suit, but that's mostly due to his poor acceleration and edgework. Ironically, I've seen posters clamour for Brady Tkachuk, but I don't see anything that Brady does that Kostin can't do. Brady has better edgework and acceleration, but I'd argue Kostin is faster in straight line speed. And between Kostin and Brady's shot, it's Kostin by a country mile.
I guess I just feel some sort of need to defend Kostin against an enemy that might not exist, but I do feel Kostin needs some sort of credit. Could he be engaged more in the play more? Sure, but I'd rather focus on what physical and mental development Kostin has gone through instead of play utilization. I don't think engagement in play is going to be what stops Kostin from being an NHL player as far as I'm concerned.
