Same. Miller was great at what he did, but also had the great fortune of playing surrounded by guys – Jackson, Mullin, Dale & Antonio Davis – who did a remarkable job of hiding his flaws either as a ball-handler, rebounder or defensive presence. He also played his entire prime for one good coach (Bob Hill) and two great ones (Larry Brown & Larry Bird). Ray never got to play for a great coach, and only got to play for good coaches (including 30 games for Hill) after exiting his prime.
Ray never had teammates as complete as what Miller had until he moved to the Celtics. Give him a decade of guys like that, and he'd have four or five titles as well as a half-dozen more series-winning shots.
Also, here is my favorite sports hot take: If Ray and Kobe had switched places in 1996, the Lakers would've won five titles instead of three. Yes, Kobe was a better player, but Ray was a better fit both on the court (he would've stretched the defense) and personality-wise (he would've more easily played second-fiddle to Shaq).
So much of sports is "fit."
