Fwiw, just to support the point above, here's age, position & level comparables higher on that list
Rank 50 - Robertson: AHL (.57gpg, 1.00pp)
"It somehow already feels like we’ve been hearing this kid’s name for YEARS." "it seems like 2022-23 is the year he needs to take that next step."
Rank 33 - Alex Turcotte: AHL (.22gpg, .67ppg)
"Part of the embarrassment of riches the Kings have going at center ice, Alex Turcotte transitioned perfectly to professional hockey"
Rank 29 - Jakob Pelletier: AHL (.41gpg, .94ppg)
"The 21-year-old had a strong rookie season in the AHL", "this is a prospect that could put up points in the NHL right now"
Rank 25 - Dylan Holloway: AHL ( .24gpg, .67ppg)
"he produced extremely well with 22 points in 33 games with the Bakersfield Condors in the AHL"
Rank 23 - Jonatan Berggren: AHL (.3gpg, .91ppg, + 1.5yrs )
"In his first season in North America, Jonatan Berggren broke the rookie scoring record for the Grand Rapids Griffins of the AHL" "The 33rd pick of the 2018 draft enters the 2022-23 season with his eyes set on a roster spot in Detroit."
Rank 20 - Lukas Reichel: AHL (.38gpg, 1.02ppg)
In the early days of the Blackhawks’ rebuild, he shines as one of their most promising prospects.
Rank 18 - JJ Peterka: AHL (.4gpg, .97ppg)
Logging an insane 28 goals and 68 points in 70 games, he showed everyone that he will be a force to be reckoned with when he hits his prime in the NHL.
Rank 13 - Cole Perfetti: AHL (.4ppg, .88ppg)
"Perfetti’s high-end playmaking abilities with speed and skill to burn continues to amaze me" , "He’s played extremely well at the pro level with 41 points in 49 games with the Manitoba Moose in the AHL"
Rank 11 - Alexander Holtz: AHL (.5gpg, .98ppg)
"Alexander Holtz certainly got New Jersey Devils fans excited last season." "The seventh pick of the 2020 draft could be on the verge of a breakout season in 2022-23."
Rank 7 - Marco Rossi: AHL (.29gpg, .84ppg)
He had a strong rookie season with the Iowa Wild in the AHL, posting 53 points in 63 games.
All roughly the same age (some are from the 2020 draft class that Robertson was his mum hanging on for one more set of contractions away from being part of) and Robertson's production matches or betters all of them. But only Robertson needs to take that next step this year, only Robertson doesn't get jerked off for how good he was in the AHL.
If Robertson isn't an "A" prospect, then I struggle to see anyone on that list being one.
