I don't know. Durant was a much better player than Ingram. A better athlete and shooter, more fluid and skilled.
They are very close in terms of shooting.
Ingram 47.9%FG 38.5%3s TS 57.3%
Durant 47.3%FG 40.4%3s TS 58.4%
And more skilled is subjective, Durant has improved a lot since he was drafted.
Durant put up more points and rebounds, Ingram gets more assists, steals and blocks on a per minute basis, Ingram plays about 31 and Durant played around 36.
Ingram is absolutely elite.
Look at his stat development

His last 9 games were much better than the first 7.
I like Simmons more because he has more flair but Ingram could very well be the better prospect. Ingram does not have real holes in his game, Simmons is not a good shooter. Ingrams position is more clear, he is a 6'10 SF with 7'4 wingspan. I think Durant is a very good comparison for Ingram, Ingram is a little less athletic I think.
This draft is shaping up better than I thought it would. Kris Dunn looks very good too, Jamal Murray from Kentucky as a shooting guard, Buddy Hields looks good. Skal Labissiere is still a high upside pick and Dragan Bender is a high risk high reward player. Then you still have Rabb, Ellenson, Trier
