He should be given the same amount of time to cook as the recent list of 1OAs Dahlin, Power, Hughes, Laf who all had very slow D+1s.Given Slafkovsky is not a typical NHL 1OA pick, he should not be treated as a typical NHL 1OA nor should the expectations of a typical NHL 1OA be placed on him.
What does this mean? He needs time to cook.
He probably should be given the same top as most players drafted top 3 in the last 5 years (Byfield, Stutzle, Kakko, Berniers, McTavish, Kakko, Dach, KK, Svechnikov).
Most of these players started to show huge development strides at the nhl level in their D+2 and D+3 years. I think it's reasonable to expect the same as Slaf's recent peers.
