The Kings had no minor league system in place when the rebuild was taking place in the mid-90s in the post-Gretzky era. The Phoenix Roadrunners developed absolutely nobody, and when they ceased operations, the Kings placed a number of prospects on various AHL/IHL teams, from the Long Beach Ice Dogs to Fredericton Canadiens to the Springfield Falcons.
The way the Kings brought prospects up was trial by fire. Aki Berg had no business being in the NHL at 18, and his struggles were visible, as he looked like a creampuff playing against men. Jamie Storr was thrown to the wolves because the Kings had nobody else in the system who can step in for Hrudey, as Robb Stauber was utter garbage, and the only other option at the time was Pauli Jaks. So because of ineptitude, they forced themselves to play Jamie Storr, until McMaster made his boneheaded move to bring in Grant Fuhr.
So you have some stupid decisions from management and coaches in forcing prospects who shouldn't be in the pros to play in the NHL, coupled with the fact that they had zero control of how their prospects are coached in the minors.
Here's a list of players the Kings drafted in the 90s who became NHL regulars:
- Darryl Sydor (traded for garbage)
- Robert Lang (mishandled by the Kings)
- Alexei Zhitnik (traded in one of the dumbest moves in franchise history)
- Rem Murray (never played for the Kings, bolted as an unsigned prospect and found success in Edmonton)
- Jere Karalahti (preferred to party over hockey)
- Kimmo Timonen (given away so that the team can protect two incompetent goalies)
- Jamie Storr (had a promising career until he got shellacked in the playoffs and never recovered)
- Matt Johnson (cement head)
- Vitali Yachmenev (one-year wonder)
- Aki Berg (the Finnish Creampuff)
- Vladimir Tsyplakov (formed 1/3 of the Kings' Soviet line)
- Josh Green (throw-in in the Palffy/Smolinski trade)
- Eric Belanger (finally a player they developed properly, somehow)
- Olli Jokinen (centerpiece in the Palffy/Smolinski trade)
- Joe Corvo (took him five years after his draft year to turn pro, and did well offensively as one of the rare dmen to come through within the system)
- Mathieu Biron (part of the Palffy/Smolinski trade, never played for the Kings)
- Frantisek Kaberle (traded to Atlanta with Donald Audette for Kelly Buchberger and Nelson Emerson)
- Brian McGrattan (meathead who never played for the Kings)
- George Parros (Ivy League meathead who shows signs that he suffered many concussions throughout his playing career based on his decisions as the head of NHL Player Safety)
That's a list of 19 players over a 10-year period. Only two top six forwards drafted, only two-three top pairing defensemen, and just one goaltender who never could hold a permanent spot as a starter. I'd say at best, they were average at drafting, though leaning more towards below average based on the fact that so few became impact players on the Kings.
