That is a simplistic view that is just not how things are done.
Top picks are investments that need to be nurtured along the way to maximize their value. Prospect development isn't a linear path - and a team coming out of a rebuild needs to be willing to make sacrifices to immediate results in order to provide the best chance at growth.
You don't need results from these kids, you need progress. It is a complete disservice to ask a 19-21 year old who has been given very, very little time to acclimate to the league and challenge a veteran for a spot on a team trying to make the playoffs. Next to none of them can do so, only the very special players make that jump out of the gate. Maybe Clarke can do it, but everybody knew that Byfield was going to take more time than the usual top pick.
Offensive players think differently. They rely on confidence and positivity to succeed. They have to believe that their shot will go through, that their teammates pass will reach their stick, that they can take that guy wide. You need to let them play to their strengths because even those aren't NHL ready yet.
Instead the Kings are developing their forwards to think defensively, that the play WILL break down and that they need to be in pessimistic positions to play it safe. It neuters creativity, and more importantly, they know that if they make a mistakes they sit for a few games while the next kid gets the same half chance at carving out a role that they were not drafted for and are not suited to fulfill.
The best way to develop skilled forwards is to let them run like wild horses and reign them in later. Let them work on their primary strengths to maximize their skills before asking them to dial it back in to "win". If any example of the new champs is to be followed, thats it. Colorado let all their kids go nuts before demanding sacrifices.
