I'd limit that to top-end centers. Who are almost mostly found in the top 10 of the draft outside rare exceptions (Kopitar, Giroux, Bergeron, Point, ROR, Getzlaf, Barzal, Kuznetsov, and Aho), and the only one of those guys drafted out of the first two rounds is Point, and Kopitar misses the top 10 cut-off by 1 pick, while Getzlaf, Barzal, and Giroux are both top 25 picks, while Kuznetsov was taken 26 and slipped that late due to the NHL/KHL issues, otherwise he's a top 10 pick . Elite wingers tend to be scattered around the draft too. The amount of the top 20 centers drafted between 1-3 is huge (Crosby, McDavid, MacKinnon, Matthews, Eichel, Seguin, Draisaitl, Stamkos, Tavares, Barkov, Malkin, Toews). Look at the best wingers in the NHL. Stone, Gaudreau, Kucherov, Marchand, and Panarin (undrafted), were all taken after the first round, and outside of Kucherov were all 3rd round or later. Even a lot of guys who don't become franchise number 1 centers but fringe first line center/good 2nd line centers tend to be found in the top 10 (Turris, Duchene, Kadri, Jordan Staal, Horvat, etc). Then you got the young guys drafted top 10, who might become legit franchise #1 centers who have proved a lot but not enough to be labeled that yet, but you can't tell yet like Hischier and PLD, and then someone like J. Hughes
D is just harder to project at that age, so where you find elite #1's tends to be much more scattered. It's much harder to examine someone who creates plays to those who have to be much more reactive when projecting how they will play when the pace of play picks up. You have guys who went top 3 like Doughty and Hedman, but then you have guys who went 2nd round or later like Subban, Duncan Keith, Josi, Giordana (undrafted), Letang, Buf, etc. We got our franchise defender at 5th overall, and a lot of other teams got their guy top 10, but its pretty clear that that high-end D can be found in the 2nd round. I'm not sure if more top wingers or top defenders come after the first 2 rounds.
That seems to be a strategy teams have adopted past the first 3 rounds, where players are expected to land an ELC. Although, I'd consider moving NCAA guys out of that grouping because if you truly get a great late-blooming NCAA guy, they have a high probability of going the college UFA route like Vesey or implying they would like Adam Fox. The amount of CHLers taken has dramatically stepped back in the last 10 years. Part of that is other regions/leagues are creating talent at a better rate than before, the other is the longer-rights situation. In year one of Dubas we went very heavy CHL, whereas last year we were NA heavy but took guys from the USHL and High-school hockey.
As for the draft, I'm curious if Tristen Robbins is high-up on our draft board. Small and skilled but with a great work ethic and compete similar to Robertson, although one is a late-birthday and the other an early one. Saw he was outside Bob's top 93. I could see him as a guy we target in the 2nd or 3rd round.
