Kostin’s biggest challenges are how he utilizes and supports his teammates. If he grows in those areas he has greater opportunity to succeed.
Him getting bigger isn’t going to magically change him into some beast that can overpower NHL players. There really aren’t many players like that in the NHL. This isn’t the 90’s game anymore. We don’t see big physical specimens taking over games.
What we do see is a need for players to work more within a system than ever before. Unless you are a superstar, there really isn’t room to do your own thing in the NHL and even those superstars can only get by with it sometimes. Kostin is not that player.
I'll concur with your assessment of Kostin's hurdles. I just wanted to emphasize Kostin's age and a similar prospect's development path...
I'm sick and tired of seeing all the "HeS a BuSt, FiRsT RoUnD PiCk NoT iN NhL aFtEr 3 YeArS, RoFl LoSeR" type posts I'm seeing with increased frequency.
I mean if Barzal, Connor, Tarasenko, Gurianov and other stars from the mid first are given their D+1 and D+2 seasons to develop before their NHL debut in their D+3 season, it stands to reason a guy taken later in the draft will be more of a project and need more development time... I mean, shit, the guy wouldn't even have been a 1st round pick at 31 a year earlier - he'd have been the first pick of the 2nd round.
I mean, we may disagree about big physical specimens not dominating today's game - MacK, Draisaitl and Ovi are hardly small, with MacK coming in at 6'0 and 200 lbs. Players no longer plow through the opposition, to dominate today you need respectable size, good IQ and speed - to overcome one of these, you need exceptional skill.
Kostin lacks hockey IQ according to some reports I've read, he's not blessed with exceptional talents in the other departments - he won't be dominant and take over games like the aforementioned players. But he's got the toolset and shows growth, he's not a 4th line grinder - I expect a solid middle sixer that may get spot top line duty as an injury fill in or if he shows chemistry with our top line guys in another 3-4 years once one or more of Perron (retires), Tarasenko (doesn't recover from shoulder surgery or declines in early 30s), Schenn (shows the power forward regression in early 30s), Schwartz (loses a step or move on). Kyrou is the only guy who projects to step up currently in our system (Sanford I've accepted is now a part of the top 6) - Kostin will have opportunities to show if he's a top 6 talent.
Edit:
@Celtic Note, this is less about your comment above itself and more a continuation of what I've been saying for nearly 2 years now.
