I'll give you my ranking based on just Pts and +/- as that's what my league uses. I really don't follow PIM at all.
Tolvanen, Eeli (Nsh - RW) - some risk he ends up back in the K this year, but by far #1 here
Dobson, Noah (NYI - D) - Should make the team next year
Jones, Max (Anh - LW) - Ducks will need to make a youth movement shortly, goes nicely with Terry and Steel
Sanheim, Travis (Phi - D) - high end potential but may be stuck behind Ghost and Provo
Kamenev, Vladislav (Col - C) - I think the Avs want him to succeed, may get based by Kaut though
Dube, Dillon (Cgy - C) - Looked great in pre-season
Formenton, Alex (Ott - LW) - Lots of talent but +/- may suck for years
Bjork, Anders (Bos - LW) - boosted by +/-
Merkley, Nick (Ari - C,RW) - needs Arizona to improve as a whole
White, Colin (Ott - C) - Should have been better in AHL but still should gets lots of playing time in the next couple of seasons
Milano, Sonny (Cls - LW) - This year will tell you a lot about his future chances, I think boom or bust
Anderson-Dolan, Jaret (LA - C) - Quality prospect
Bear, Ethan (Edm - D) - potential decent pts with other categories helping him
Aston-Reese, Zach (Pit - C,RW) - just needs to catch on with the right super star but if he doesn't I think he busts
Groulx, Benoit-Olivier (Ana - C) - I haven't seen enough yet
I am not sure the rest of these guys will be fantasy relevant at all.
Kuokkanen, Janne (Car - C,LW)
Geekie, Morgan (Car - C)
Laberge, Pascal (Phi - C)
Skarek, Jakub (NYI - G)
I Like the list, but i'd change it around a bit in terms of player upside (ignoring teams since most of these players will be bust fantasy-wise), comments on the changed players:
Tolvanen, Eeli (Nsh - RW)
Dobson, Noah (NYI - D) - Looks like a huge steal for the Islanders
Sanheim, Travis (Phi - D) - Great prospect and Philly will be a stacked team sooner than later.
White, Colin (Ott - C) - Played for a crappy AHL team and will play for a crappy NHL team, but high-end potential.
Merkley, Nick (Ari - C,RW) - Really like his potential and has some potential young, quality players to play with. By no means a guarantee though.
Formenton, Alex (Ott - LW) - Think he's worth a gamble if you want a high upside prospect, but a risky pick and a few years away.
Jones, Max (Anh - LW) - Definitely high upside if he puts it together, but I think he was a product of a stacked Knights team. I personally wouldn't bet on him, simply doesn't have the hockey IQ.
Milano, Sonny (Cls - LW) - Think his floor is a 20-30 point NHL player, ceiling is a bit more questionable. A change of scenery to a team with less depth would be highly beneficial.
Bjork, Anders (Bos - LW) - Huge upside IMO, but injuries and a stacked Bruins team will make it hard for him to find a top 6 spot. As like Milano, change of scenery would be beneficial.
Kamenev, Vladislav (Col - C) - If everything goes right, his ceiling is a 50 point #2C, but i'd bet he'll be closer to a ~30 point #3C if he can crack the NHL.
Dube, Dillon (Cgy - C) - Seems more like a very safe, hardworking player but still has some nice potential.
The rest the OP listed are still decent prospects and I pretty much agree with the sentiment on those players. At least at this point, i'd say they aren't too indistinguishable from one another (besides older prospects like ZAR, but you already made the points).
