Jordan was significantly more efficient in the playoffs than Lebron has been, and Jordan played against superior competition in an era where the rules were nowhere near as friendly to wing players as they are now.
Increased charge area, 3 seconds rule, hand checking rules, all significantly protect wing players. There is a reason why Lebron shoots so many more free throws per shot attempt than Jordan did.
