I'm not sure what you mean by "post-expansion", by my reading of the wiki timeline (https://en.wikipedia.org/wiki/Expansion_team#National_Basket...) Jordan came in during the middle of what would become the longest drought between NBA expansions. (And considering the rest of the league at the time, it's hard for me to get my head around what "incredible for the era" could mean)

Jordan's major wins - his 91-93 championship run - and thus a fair portion of his legacy, came post-expansion of the NBA by 4 teams.

It's not a knock on Jordan or the Bulls, but there was a talent drought for a few years. The Bulls took full advantage and Jordan shone.
