The thing is, the amateur scouts were able to pick out Iafallo where he was not only NHL ready right away, but he was the top line left wing right away.
The amateur scouts can identify talent. As it stands, an undrafted free agent who didn't go through the Kings developmental system is the top line left wing.
He was also 23 years old when he signed in April 2017. That's a world of difference from 18. By the time the season started, he was about 3 months away from being 24. Since we're talking about him, Kempe won't be 24 until September, and it seems like he's been in the organization forever. That's how old Iafallo was. I believe his original draft year would've been 2011, and not a soul picked him. Also, did anyone expect him to be the top line LW, either when he signed, or going into camp? Have some complained for 2+ years about the fact that he's been on the 1st line? Or at least talked about how the team didn't have a better option for 1LW?
As a whole, the top player they've developed this decade is Toffoli, who was an inconsistent 2nd line winger when he was on the Kings. I don't expect them to make a line-up of all-stars, but one difference maker up front who is a bigger contributor/role than a 23 year-old undrafted free agent or a 35 year-old skilled, but grinding winger is not unreasonable.
Between 2006 and 2009, the rebuilding years, other than the #5 overall pick, they drafted one forward who could be considered close to a difference maker, and even that might be a stretch. More of a skilled but grinding winger.
Lombardi didn't draft Kopitar, but can you give him/his group credit for developing Kopitar? Spent one more year in Sweden after being drafted, and is the son of a coach. Came to the NHL, and didn't spend a second outside of it. That's not development, he was just ready. Same with Doughty. Quick, Muzzin, different stories. Brown, without the lockout, I don't know that he ends up in Manchester for a year. Not that that was in the DL era anyway.
So to just make it clear, the staff isn't bad. They don't ruin careers. There's just not one case of taking a forward to the next level. If they need top picks to churn out one top 6 winger, then the organization is going to go through a cycle of mediocrity every few years where they need to struggle again to have a top pick save them. That's my concern.
Brown-Kopitar-Williams
Penner-Richards-Carter
That's a 13th pick, 11th pick, 28th pick, a guy that cost a 1st, another guy that cost a former 5th overall pick, and was the 24th pick himself, and another guy that cost a 1st, and a former 3rd overall pick, and was the 11th pick himself.
Gaborik-Kopitar-Brown
Pearson-Carter-Toffoli
That's a former 3rd overall pick, an 11th pick, a 13th pick, a 30th pick, a guy that cost a 1st, and a former 3rd overall pick, and was the 11th pick himself, and the best pick of the Kings since 2010.
Not a ton of mid to late round picks being developed for teams that won the Cup.
If you end up with a top line player from mid to late round picks, by either luck or incredible development, that's a luxury. That's the exception. Not that 1st round picks don't sometimes bust, but the vast majority of the real talent on your team is going to come from the top of the draft. Doesn't have to necessarily be a top 5 pick, but you're probably more likely to get that guy at 12 than 52, even if your development staff is made up of complete strangers who were blindly hired on resume alone.
