KK has looked a lot better offensively compared to the last couple of years, and he likely tops out as a 50-60 point elite 2-way Center. But his defensive game is exceptionally mature for his age.
To the same degree as him? Probably nobody who has been drafted. To go from him "not an NHL option" to probably a top 5 C in the league, it just doesn't happen. Tage Thompson is a unicorn in that regard.
Likely no one as there really isnt a case like his in history, man sucked 3 years ago and likely should have gone unprotected in the seattle expansion draft lol
