Dahlin and Hischier are too high imo

how would you rank them then?

After 6 there’s a big drop off

for sure. slafkovsky looks to be developing really nicely at least so hopefully he'll make this list look better down the line

If we are going off of their career by the end of it? They are probably both right above Power. Slaf and Celebrini I believe will be better

Dahlin is an elite 1st pairing defenseman, there's no way he should drop on this list. He plays against the best every night. Here's a simplistic view of the first 2 seasons post draft (to match Slafkovsky's career so far).

Hischier: 151, 37-62-99 +10 (0.66 P/GP)
Dahlin: 141, 13-71-84 -20 (0.60 P/GP)
Slavkovsky: 121, 24-36-60 -32 (0.50)
Power: 87, 6-32-38 +13 (0.44)
Hughes: 117, 18-34-52 -29 (0.44)

Honestly Power looks like the better pick right now too. Hughes had a pretty weak start to his career though so maybe Slafkovsky can become an 80-100 point guy, but I don't see the elite skill that Hughes has.
