Imo he is never a better defensive option than Rudy. I think Rudy can guard Morris or Jokic or hell, even Steph curry better than cousins canIt's a question I'd love to hear an honest answer from Quin about.
I agree Cousins and Gobert at the 4 and 5 would be impossible for opposing teams to defend against. He would also be a better Defensive option against the Marcus Morrises of the NBA. We could always use more rebounding - especially against the Lakers and Clippers, and his 3 point shooting 34% over his career (38% w Pelicans) would be a natural fit.
