Rudy would get abused by good post players. That is his weakness now. Strong tall post players who can just bully him. Rudy is better built better for todays NBA. Shaq, Malone, Robinson, Barkley, Ewing, Hakeem, Kepp, Divac and Alonzo would all be rough for him to defend. The game was so much more physical I think he would have got shoved and bullied a lot more then, not that they are the same but kind of how Shawn Bradley was.
exactly, guys like Gobert would get bullied by stronger guys in the old NBA ! He is good in today's NBA because he knows how to defend space, and this what matters : that he can cover ground and alter shots by defending space. But his man to man D is weak in terms of post play, just look at what Okafor did to him... no in the 90s guys like Okafor or Cousins would be the monsters.
