I don't think that this should be considered as a historic feat in 76'ers basketball history. Not even in the top 10 in my opinion. Those two you mentioned is really iconic because it was done in the spurs on the moment.
But it could be a consider as Simmons personal achievement but not something that could be consider as historic. The Daryl Dawkins dunk that shattered the back board (pre-Shaq era) was one of the best.
If you don't know Ben Simmons you will really questioned that historic thing but I think everyone here knows the ability of Simmons in 3 points shooting.
Simmons is known for the unusual trait that a Point Guard should have and that is his inability to made a 3 point shot. It was 3 whole seasons without a 3 point shot made and that was rare.

It's an obvious sarcasm.
Despite that, he is still having a great stats in points, rebounds, assists, and steals, so he is valued more on his defensive ability and if he learned to improve his 3 point shooting, he will turn himself to a complete player and that's so scary.
