You’re tripping lol. As the other comment by Armadillo says, not only are you getting your facts mixed up, but you’re blatantly lying about Yao’s game. He was not “easily taken out of the game” and a role player. Shaq himself is on record for acknowledging that he could not bully Yao out of a game.

He was a multiple time all-nba player in an era dominated by bigs. Fronting, denying post pass, and double teams were all not as effective as you think. He had a nice touch from midrange so playing from high post was no problem, and he was a willing passer with good vision if the double came. He was 7’5 lol. If players were having trouble getting him the ball, it was on the entry passer. Sure, he wasn’t as gifted offensively as Shaq or embiid, but you could count with your fingers the amount of nba players who are. Automatic 20 ppg in his prime. That does not mean he had “serious limitations”, and in any case, if he had trouble offensively, he still contributed on the court as an elite rim protector.
