I agree that Edvinsson's "consensus" position would be in the top ten. But his consensus position would also be below players you just stated you do not consider to be #1 forwards like Eklund, Beniers and Johnson.
Recently, I did my own research into the consensus. I took the rankings of several major scouting bureaus and a few of my favorite draft analysts. The resources I used were TSN (McKenzie), hockeyprospect.com, McKeens, The Painted Lines, FC Hockey, Sportsnet, Pronman, Wheeler (both The Athletic), Cam Robinson (Dobber Prospects) and myself -- for a total of 10 rankings, to make the math easy.
Doing the math, this is an accurate consensus ranking for top players at every position:
C
Beniers: 3.0 (1st- McKeens, Ives)
Lucius: 10.5
RW
Guenther: 5.8 (1st - Pronman)
Lysell: 11.1
LW
Eklund: 5.9 (1st - Robinson)
Johnson 6.8
RD
Clarke: 5.7
Ceulemans: 22.8
LD
Powers: 2.7 (1st - TSN, HP, TPL, SN, Wheeler)
Hughes: 4.1 (1st - FC)
Edvinsson: 8.1
So, we can say that the consensus sees Edvinsson as just shy of the likely top 7 prospects, with their total of #1 overall rankings in parenthesis --
1 Power (5)
2 Beniers (2)
3 Hughes (1)
4 Clarke
5 Guenther (1)
6 Eklund (1)
7 Johnson
8 Edvinsson
Essentially, this gives us a pretty good idea about how the top of the the 2021 draft is going to go. I think we can pretty much guarantee that Power is gone in the top 3 and Beniers in the top 3 or 4. There's a little more leeway for Johnson or Edvinsson, who could both potentially be top 3 picks but also both potentially fall out of the top 10 altogether. Those middle guys (Hughes, Clarke, Guenther, Eklund) I feel we can guarantee as top 9 picks, and any of them could also surprise at #1 or #2 overall -- depending of course on who is drafting.
Personally, I like Edvinsson and Johnson a lot, but I'm not reaching for either of them at #4 or #5 because, quite simply, there will be better prospects available -- both in my opinion and the consensus opinion. Even if all three of the top D were gone (Power, Hughes, Clarke) and the Devils were drafting 4th, why would I reach for Johnson or Edvinsson over Beniers or Guenther? Sure, they are at positions the Devils need more, but I'd be taking a greater risk (Johnson) or passing on superior upside (Edvinsson) at a very high draft slot.
I'd say in this scenario, the answer would be to draft Beniers, and then use the Islanders pick (likely #20-#26 range) to take a player of greater positional value. There could be some highly regarded players there at the Devils positions of need, D (Ceulemans, Svozil, maybe even Lambos) and LW (Chibrikov, Sillinger, Othmann, Robertsson, Pastujov, Olausson, Rosen, L'Heureux).
