My posts were predicated on ONLY Curry (not his whole team) being transported to that era.
Again, if we transport Curry in a vacuum 25-30 years ago, he wouldn't have that spacing because no one (besides himself) was shooting that much or that well from deep. So yes, the lanes would be packed, you'd have multiple big men inside, and his primary defender would be able to play him as a shooter, and would do a much better job of it than defenders today due to handchecking etc. (plus, again, defenders today can't play him strictly as a shooter for reasons previously mentioned).
If you want to believe that Curry - not a great athlete and only 6'3" in size, is going to A) get in the lane as frequently as he can today, and B) finish over legit bigs like DRob/Dream/Shaq/Mutombo/Zo etc. at a 65%+ clip like he does today, then that's on you. But it's a fantasy. Again, there's a reason no player under 6'6" was dominant in the paint back then besides hyper athletes like Jordan, Drexler etc. Curry would have next to no inside game back then, and teams would play him as a shooter. 23-26 pts/6-7 ast/60-63% TS best case scenario for him. Still an all time great, but none of the hyperbole we see today.
