I said none of the above for different reasons.
For the drafting, 2007 was an exceptional year, so it's an outlier, I am not sure the period 2008-2016 was that abysmal, but it was clearly poorer.
We know the reasons for that. Bergevin more or less was drafting the first round on need and size. So he would ask "what is the best tall and gritty defenseman, or center this year?". Then he would trade the second pick for some player usually.
So the first picks failed, and not surprisingly, not much came up of three and higher because it rarely does, but there were a few exceptions and overall in the circumstances, the draft was pretty decent. What's peculiar is nobody made it into the farm. Either they made it in the NHL or they were not in the picture, so development was not existent.
There is one exception, Sergachev in 2016 who was drafted to trade. KK year was a good year and it seems Bergevin stopped trading out seconds the year before in 2017, but collecting them because he was in "retool" mode which was a variation of "the plan". So that means more players and a possibility of development.
I can't say it turned a corner, we know 2018 was a good year, 2019 is harder to tell who makes it, but Caufield and Harris already make it a good year as well. Now clearly they are not the typical draft because Caufield is small so there was a shift there in focus.
It's too early to tell for the other years, but it looks good. Maybe they now take into account things like skating ability or offensive ability more seriously. Still there is not a lot of forwards that look great except Mesar, maybe Roy.
So I am not sure about whether things really have changed. They still tend to draft big players with character and hope they will get good offensively. It's what the last two first round picks suggest, so I am not ready to claim there is a deep change, it could just be the luck of the draw, or some scout some year making a good pitch for a guy like Caufield, because he is the only true outlier and his talent was totally obvious.
As far as development, I can't tell. It's not like the young players spent much time in the AHL, so as far as I can tell, the farm team is not really doing the work it should be doing. It seems more like a place where the extras are put for roster reasons, not a place where you develop the future per say, but I could be wrong. We will see in a couple years if it becomes what it used to be and should be.
In other words, I don't see any drastic change right now to the past. Hughes still exchange good draft picks for players, seen to favor size and some sort of attitude to life and general good humor. He tends to think it's fine to rush players without development and it does not seem to be the actual focus of the AHL team to do that. There is no doubt there is more drafted players that make the team though, but I can't totally explain it outside of the trading of picks thing.
