It's pretty impossible to predict. Who would've thought Barzal, Connor and Konecny would fall so far last year?
If I had to take a stab at it though I'd say Gauthier, Fabbro and Sergachyov. Although it depends how you rank them. Some guys have Gauthier as a borderline top10 pick whereas others have him around #20. Basically when I'm saying he might fall I'd consider him falling would be if he's taken around #20 rather than around #10.
I guess the same is true for Fabbro. Many guys had him in their top10 at the beginning, and perhaps even the midpoint, of the season but now he seems to have fallen into the 20's already by many scouting agencies. So if he's taken around there I guess it wouldn't be so much of him falling on draft day but rather in the months prior.
Personally I think McLeod should be a guy who falls compared to his draft ranking but I just don't think it will happen because he checks all the boxes for what scouts/GM:s like in a player. I think maybe Tkachuk should fall a little too but with his bloodlines and production I don't see that happening either.
So going on traditional stuff on what might make a player fall I'd suggest Keller will be the one to fall the furthest of the top ranked guys, just because he is lacking in the size department. You saw guys like Bracco, Merkley, Konecny and Barzal fall last year and they're all on the smaller side so I guess that's the most reason a player falls.
