I agree re Davies. I do think the Wayne Rooney paradigm haunts all of our youngsters. Rooney was ostensibly a fully rounded, world class player at 16. He didn't have bad games. You always get the sense if a player isn't quite to that level, you sense they are written off. Honestly, the whole country could go another 50 years and never produce as rounded a footballers as Rooney was at 16. Liverpool talk a lot about Kaide Gordon being the best 16 year old in the country (I'd question if he was that far ahead of Small but it's a slighty academic point) but he's about 5 ft 6 and tiny. He may be the best, but he is miles off where Rooney was. So there has to be a bit of realism. We may never see a young player of Rooney's ability again come through our academy in our lifetimes.
I tend to have a couple of objective measures I have for young players to see if they've "made it". I know Steve Heighway at Liverpool used to use the 100 league games measure, so I like that one, or generally 50 league starts/100 domestic appearances. I use both of those, have they got to 50- you can start discussing it, if they get to 100 starts then they are cemented in. Davies has 84 starts and 123 PL games, so for me he's made now.
As for the current crop, I suppose I will qualify that a little bit. The current under 18's age group, in honesty I wouldn't categorise in that way, it was more a comment on the 17's and the subsequent 2 years below. I've given a bit of an outline on the players a few ages back, but for me Price, Whittaker, Welch, Small, (17's) Heath, Romayne, Barker, Pickford, Tierney, Metcalfe and Lawrence are all at a higher level than what we've had in the 5-6 years that seperate Davies year from that year group.
The wider question and I suppose you could call it concern, is that we produce a lot of players of a certain type. Medium build, decent technically, a bit one paced, hard working and disciplined players who can put their foot in. Essentially a lot of central midfield players (but not in the Pep way!). The academy take great pride in lads getting careers and generally ours do that better than most other teams, but not at Everton, and beyond a potential recruitment advise to new prospective parents I don't really see the advantage of it. Lower league clubs have little money to spend, and have less now. It's one of those things that gets trotted out, a bit like when Unsworth spoke about "keeping the under 23's team together" which when you hear it makes no sense. I don't know how Everton benefit from it, and making players for the rest of the league, that will invariably be given away for a nominal fee doesn't work for me.
I think you are right about Small and to a degree it's what makes Onyango stand out. Small is very powerful, quick and strong, which makes him stand out. Onyango you are right to say is quite an ordinary player, but he's 6 ft3-4 at 17, who knows where he will end up. So he has certain advantages other players don't have. Overall, recruiting on physicality for a club like ours is probably a bit underrated and we should do it a bit more. We used to do it a lot more and while it got a bad rep, overall it suits us.
