I have as much respect for the history of the game as anybody, some of my favorite all time players are older like Hakeem, Jerry West, Sabonis, Dr.J, Worthy, MJx David Robinson etc so that narrative is tired.
And the numbers tell you that Giannis is having a better individual season than '99 Duncan because he is.

I don't see what's so hard to believe about that considering that Giannis is a 7 foot PG while being an elite defender while Duncan played with a HOF C, HOF coach and a great team in general.
Talking about you consider stats and "outside" facts but you didn't even consider that.
Not only that but I shortened things to the 3pt era and use pace adjusted #'s so once again, that narrative is wrong too.
I don't need to rely exclusively on stats, they just back up my eye test with fact, which you can't say.
