Well, the names you listed I would rank: Keller, Strome, Hischier, Patrick, Point and Meier. But don't forget Puljujarvi here who I would have probably right after Keller. Dubois also deserves consideration but more so for the pick #16 and not the 9th overall pick. And then there are D-men like McAvoy, Sergachev and Chabot to consider there as well. I'm too lazy to put together a complete list for you but if you can figure out a top-25 or something like that, then I can try ranking them.
