Totally, as has been discussed ad nauseum! It seems like a lot of folks have locked into 2 of the top 6 D as the ones they talk about "at 2OA" or "after Celebrini and Demidov" but basically any list is a complete shuffle of Dickinson, Silayev, Levshunov, Buium, Parekh, Yakemchuk. Teams likely have their own opinions based on what they like and need, so predicting the top 10 is crazy hard.
Demidov could go 2OA or 9OA and you could understand why. Most of this is because of the big slug of same-tier but different-style D men, but you also have to consider the odd cases of Lindstrom, Catton, and even Eiserman and Iginla at F. It's just gonna be a wild first 15 picks.
