The 2018-2020 drafts don’t have a lot to offer in terms of bottom 6 and big body defensive options though.
That's just not true though.
Even with the prospects from these drafts still developing, we already have 2 NHL defensemen and 1 NHL forward from the 2018 draft.
We'd likely have 1 more NHL forward from 2019 if they didn't get injured, and 1 more NHL forward from 2020 if they didn't get brain cancer.
And many more developing well.
We do also have some bigger prospects from those drafts (Holmberg 6'0", 200 lbs... Kral 6'2", 200 lbs... Kokkonen 6'0", 200 lbs... Villeneuve 6'2"... Schingoethe 200 lbs...), but again, you don't need to be that for bottom-six/bottom pair roles, and again, we didn't need a bunch of giants in the 2018-2020 drafts because we had already drafted a bunch of giants in the previous few drafts. Aren't you the one talking about diversifying your pool? Or does that only count when you want more of the prospects you like? And why are you ignoring the 2021 and 2022 drafts?
Think that’s why we’re seeing Knies get earmarked for promotion and longer shot mature prospects like McMann get to the Leafs before their picks.
Again, Knies is earmarked for promotion because he's a top tier prospect based on his skills. McMann is one of many options (some of which were tiny) to get a look this year and look good. McMann is 26. I don't know why you're acting like it's a surprise that he may be further along the development train than some late drafted 20-24 year olds. Also, McMann is a good example of bigger players brought in through means other than the draft that don't get counted.
Would have made a difference if Korshkov and Rasanen and Gordeev had actually panned out.
Yeah, but at least we didn't draft tiny little Debrincat instead of Korshkov, right? That would have been horrible! He clearly has a "non NHL body", and will never be successful in the NHL.
Talent also needs to be translatable into actual NHL roles though. No doubt Timashov, Bracco, Dzierkals, Robertson, Der-Arguchitsev, we’re and are high ceiling players on draft day. But they also have non NHL floors.
I don't know why you're naming draft picks from 2015, but nearly every prospect's "floor" is not making the NHL. That doesn't mean anything. When you're talking longshots and projects, the chance that a smaller player will either grow or learn to excel as a smaller player in the NHL is bigger than the chance that a a big guy will suddenly develop critical skills post-draft and be able to maintain a high level of play when not physically dominant over their peers like they have been for most of their lives.
