Grigorenko -> reminds me most of Getzlaf, minus the physicality, and with more of a shoot first mentality. Big differences, but I still see Getlzaf more than anyone else in terms of size, skating, puck handling, vision, etc.
Nichushkin -> reminds me of Nash
Trouba -> reminds me of Bogosian. FWIW, I think both Bogo and Trouba play a similar style to Shea Weber, though obviously they both have a long way to go to be as good as him. Trouba has been the best dman of the tournmanet so far, on any team, from what I've seen
Rielly -> not so much this tournament, where he's been playing a more cautious game, but he reminds me most of Letang, with less physicality and a less deadly shot. Also reminds me a bit of Karlsson, again without the bomb of a shot
Galchenyuk -> I see Hossa very strongly when I watch Galchenyuk
Grimaldi -> smaller Jason Blake. Great speed, great hustle, nice shot, but seems dumb as a rock out there, looks to shoot literally everything. Does not use his team mates well at all
Yakupov -> offensive style/abilities are similar to Ovechkin, but smaller and not as dominant
If Trouba and Scheifele pan out anywhere near Weber/Seabrook and Getzlaf/Spezza, I will be a happy Jets fan.
From what I knew of Trouba before the draft I thought he was strong on D and lacked offensive skill. After watching him play, he is an amazing D-Man. All around good in everything. I think that Trouba will become a number 1 or 2 D-Man for the Jets.

Galchenyuk is nowhere near Stamkos in terms of goal scoring.
He might peak at 40 goals, but I doubt he ever hits 50, let alone 60.
I did mention ceiling.
That being said, it depends what type of players will surround him. Stamkos benefited from playing with the likes of St-Louis and Lecavalier - veterans near the top of their form when he busted in the NHL. I don't see Gally having the same support system.
Grimaldi reminds me of an even more sefish Max Afinogenov with way way less production. Grimaldi has a better future as a speed skater or figure skater. Something where the focus is on skating and not on having to actually get a puck into a net.
