I have Fimis more in the Ludwinski, Del Bel Belluz, Beck, and Haight range. Definitely not a 1st round talent right now, and may not be anything better than borderline 2nd round right now. DBB and Beck's stock may be rising after being key members of a very successful Mississauga squad right now though.
I think you have a good bulk in that late-1st/early-2nd range with Hughes, Kasper, and McConnell-Barker as less elite, but more well-rounded players. Gustafson, Ostlund, Bystedt, Zhilkin, Poitras, Kulich, and Goyette have a little bit more high end skill, but maybe need to work on rounding out their games.
The problem I have with all of them right now is that none of them really stand out as clear cut late 1st round quality picks. A lot of them seem more like 35-55 guys than people you would take in the mid-late 20's (which is where we will be if we don't make a deep Cup run). It is also very possible that guys at other positions will be BPA over them. So it may make sense for the Leafs to trade down and add a few picks than to "reach" for any of those guys.
The USDP center trio of Cooley/Nazar/McGroarty are all likely out of reach barring some kind of drop off or injury. Out of the three, McGroarty may be able to get to us. Not totally unreasonable.
One guy who is ranked somewhat high but may drop is Nathan Gaucher. His offense hasn't quite taken off enough for him to live up to the Getzlaf comparisons, and so he may drop into the late 1st round as well.
It is also possible that Slafkovsky, Lekkerimaki, and Lambert may drop enough to get to us, despite receiving a ton of hype from the online scouting community. The problem is that all are likely going to end up as wingers in the NHL.
Just want to put it out there that it may not be the worst idea to add in other areas outside of center however. We have a lot of quality LW's, and some of them may be able to move over to RW, but I don't think it would hurt to add another quality LD and RD to the pool and I would not hesitate adding a high end RW prospect to the pool. Of course, this team could also use another goalie prospect, but I am not loving the crop this year.
