Quoting: LoganOllivier
2 things
1) You are right Faulk is a flawed right handed puck moving defenceman. That isn't worth all that much, or at least it shouldn't be but some GM's are terrible.
2) Kassian is worth literally nothing. Also a 1st rounder from Edmonton isn't 20th or higher, it's likely going to be another top 10 pick. Even with this trade the team is still so weak. Edmonton has McDavid and a about 8 other players worth keeping around, the rest is a collection of guys who wouldn't make a good team period.
The Pacific is still relatively weak this year, this is a wildcard roster provided that the Central division mutilates itself with the three superteams at its helm. The only "locks" for playoff contention in the Pacific are the Sharks and Knights. Can the Kings and Ducks overcome father time? Can the Oilers and Flames sort out their goaltending woes? Is Arizona for real? Vancouver's already well out of contention.
That means there's a good chance that the Oilers 2019 1st is likely to not be a top-10 pick. Somewhere between 11-20 is a lot more reasonable. Ottawa, Detroit, Vancouver, Montreal, New York R, Chicago, and New York I are objectively worse than the Oilers. Unless they win one of the lotteries, there's probably more value in two picks than one.
Kassian's worth less than Faulk yes, but it's not entirely
nothing. Carolina - specifically their ownership - values grit, toughness, and hard work. I'd say according to the Hurricanes, Kassian's worth approximately a 4th Round Pick.
