To add something that I never really mentioned... Trae Young have been practicing 2+ hours everyday since he was a little kid. And there's soooooo many others just like that now. That increases competition, although some of those kids plateau in middle or high school.
Point being, Trae's elite fundamentals and basketball iq get discredited for whatever reason. Same with Ja Morant, who is a film junkie. There is also so much more generational knowledge being passed down from former college players (Trae Young dad), overseas hoopers (Justise Winslow dad) or NBA guys (Darius Garland dad, Jermai/Jerian Grant's father/uncle, Austin Rivers) to their sons.
I even think I was a little off base by not giving today's big men enough praise. Ayton, Jaren Jackson, Bam, Sabonis, Karl Anthony-Towns, Porzingis, Giannis, Nurkic, Jokic, and Embiid are all 26 years old or younger. Anthony Davis is 27. Zion is 1 of a kind but Pelicans have been using him at the 4 and sometimes the 5. Jonathan Isaac is one of the best defensive players in the league. Lot of the big men of yesteryear were never asked to switch onto guards in PnR situations. Not saying they couldn't possibly do it, but there wasn't much switching back then. Andre Drummond is a 26 year old 2x all star whose value is diminishing partially because he can't switch on the PnR. His strengths would be more apparent if he were dropped off in the 90s.
