Not sure how I would rank Cowan, Minten, and Greb respectively when it comes to our top prospect. My gut tells me Greb is ahead of both of those guys. What has done, and continues to do in the K is pretty spectacular. Like previous posters have mentioned, the KHL is no joke. It is incredibly difficult for players his age to even get regular minutes, let alone produce at the rate he has.
I think what is the most appealing about those 3 prospects is that they all possess very different qualities and they project to be different style players at the pro level. Not every player can be a top 6 forward and get PP1 minutes. We need a full compliment of prospects that are willing and able to adapt their games to fit our needs.
You look at Robby as a prime example of a player who has kind of been boxed out of a roster spot because of his inability to adapt his game. There is no doubt in my mind he would be an NHL'er on more than half of the NHL rosters at this point, but he does not fit the need for us.
Guys like Minten, Cowan, and Knies all seem to possess a bit more of a malleable profile, whereas Robby and Greb kind of fill that skill profile. It's a fairly good balance in our top 5 forward prospects IMO.
Not to mention, I do believe Greb has a bit of snarl to his game if I am not mistaken, and unlike Robby, he has the frame to play that way at the pro level.
I do still have hopes for Nick, he has NHL skill with a Josh Ho-Sang like brain. Until he figures out that less is more at the NHL level, he will likely not cement himself on our roster. I am really pulling for him though. He is a tremendous talent that has all the tools to become a really good player. He's just gotta put it all together. He is still incredibly young, and we should not even come close to writing him off.
