Sounds like the big difference is that DL verbalized a lot of his thoughts and visions to access bloggers and media (never forget Teddy Purcell filling the 1LW "box!") whereas Luc and Blake are keeping it relatively behind the scenes if that's the case.
Okay, I'll try to recall the important bits I witnessed that day since I was lucky enough to attend...
Boxes and charts: There absolutely are boxes which we saw for every position on every line and every defensive pairing and goaltending. There was also a similar chart with each position (1C, 2C...1st Pairing D, 2nd Pairing D etc) and how many prospects they think project into each slot and how many they want in the pipeline for each. For example, they believe they have a definite 1C in the pipeline, but want 2 total at least. They also presented a chart with the typical percentage chance a 1 to 10 overall (as well as other draft ranges) draft choice plays in the NHL in year 1, 2, 3, 4, 5 etc and how some of the draft choices have either broken into the league before their projection or are still marinating.
Importance of draft choices: Luc stressed the importance of collecting draft choices over the next few years to make the team younger (said the Kings are among the oldest teams in the league). Mentioned that they're trying to add even more picks in the upcoming draft. There was a bullet point that I liked seeing, which is that older players are blocking the path of younger players. That's part of the impetus for making trades. Luc also mentioned that there are 13 (I think) expiring contracts (specifically said "I'm not going to name names") on the roster till the end of the 2020 season. I think we're all annoyed that Desjardins is overplaying the vets and limiting the ice time of actual producing youth for who f'ing knows why.
Muzzin trade: Luc and Cheeseman explained the thought process behind the Muzzin trade. They showed a chart of comparable trades over the years and the return for each. Also some sort of ranking system where once they felt that the offer(s) for Muzzin broke a particular threshold, it was time to make the trade. They 100% did ask for either Liljegren or Sandin (said it was their top D-man prospect), knowing they'd likely get rejected. But that the 1st was mandatory in any trade scenario and the addition of Grundstrom and Durzi pushed the offer into the pull the trigger now category. Mentioned there wasn't much of a market for players with term this trade deadline and that only Muzzin and Montour were players that were moved with term left on their deals. They feel they can get more for certain players on the roster when they're rentals next season.
Style of play: This was an interesting discussion. Basically, showed footage of plays in the league when the Kings were dominant with their style of play. Then showed footage of the same type of plays and how the plays are all penalties now. That the Kings were built around a particular philosophy that worked (mentioned not losing a game in regulation for 2 seasons when leading after 2 periods), but is no longer going to in today's NHL. It was eye opening on how checkers and defenders are so afraid to engage with puck carriers now for fear of penalties. Way less stick activity with defenders electing to leave their sticks on the ice instead. Luc mentioned that the Kings need to start filling the roster with players who can take advantage of the new rules and when showing players dance down the middle of the ice said "We don't have anyone who can/will do that" laughingly.
New coach: Not a lot of meat here, but there was some discussion about what they're looking for in the next coach. Didn't outright say WD is goners, but it was obvious that they're looking to replace him with someone who can not only handle vets, but also will develop young players. Luc said "Nobody's looking to hire a head coach whose philosophy is to win 2 to 1 anymore."
Anyway, I'm sure there is more that I've forgotten. The leadership does know that changes need to be made and where the franchise is deficient. Now, how they execute in addressing the need for change is going to tell the tale on how this team looks in 3 seasons. I don't post here much now, but if you see any value in this post and want to cross-post it in another off-season plan thread so it doesn't get lost in the Sean Durzi signing thread, go for it.
