Jokic is 20/10 and 50% for the 2nd straight year.
KJ only has 7 seasons of at least 70 games. 1 is his rookie year. That simply isn't a long enough career in my view unless the guy is just a monster, which KJ was not.
And these stats show why it is hard to compare eras. Take Oscar. He only shot 50% or better twice in his career, but he finished in the top 5, four times and top 10, 4 additional times in FG%. In 61-62 he finished 4th in FG%, led the league in apg at 11.4, finished 5th in ppg at 30.8, and 9th in rpg at 12.5. Yet because his fg% was 47.8 he doesnt show up in that stat. Also that 11.4 apg was 3.4 apg better than Guy Rodgers whose 8.0 was 2nd in the league. Era comparing is just hard to do, which is why things like all star appearances, all nba teams, mvp voting, dpoy voting, etc. in my view are better gauges and comparison tools. They simply just show how the player was thought of in his time.
