I think the talent level is pretty good at certain positions.
At PG you have players like Irving, Lowery, Dragic, Teague, Thomas, Jackson, Rose, Wall, Curry, Westbrook, Paul, Lilliard, Conley, Rondo, Rubio and more. I would say this position is deep, and you have a few elite HOF players.
SG doesn't seem as deep. A declining Wade, Derozan, Bradley, Butler, Beal, Thompson, Harden, maybe someone like Gordon when healthy.
SF position seems very strong at the elite level. James, Durant, George, Leonard, Anthony, then other good players like Crowder, Wiggins, Gallinari, and Giannis.
PF you have Love, Bosh if healthy, Milsap, Porzingas, Green, Aldridge, Griffin, Dirk, Davis, Favors...
at C you won't find any Centers like the ones from the 90's but Cousins is pretty talented. Horford is pretty good, Drummond, Lopez, both Gasols, Howard, Jordan, and the youngins in Philly. Lol
I would say the talent level seems healthy especially at the elite level for PGs and SFs.
