There's a good chunk of players on the current Kings roster who will likely be gone and forgotten about over the next couple of years. I can identify at least 10 players right now who likely fall into that category:
Maatta, Amadio, Wagner, Moore, Lizotte, MacDermid, Frk, Luff, Athanasiou, Alt.
On top of that, you have Carter and Brown with two years remaining on their deals, and Quick with three years left, plus Iafallo is an impending UFA whose long term status here is undetermined...
There's going to be a lot of turnover coming up, and the next generation of Kings need to step in and play pivotal roles pretty soon. The holdovers and rotating list of castoffs aren't going to be keeping those spots warm for very long.
