That doesn't change the fact that Shaq was a rookie, that's like me posting clips of Leonard getting owned by Gay or Durant years ago. But it's not like Parish stopped Shaq, Shaq still tore him up despite those few highlights. Ewing used to own Mourning when he was younger (Mourning was a rook in '92), sure, but as the years went on Mourning continuously outplayed him, he probably had a handful of good games against him.
The NBA is a cycle, Rooks take around 4 years to first reach their primes and fill out, another 3 to finally peak. Their primes eventually run out, but it's not like they stop progressing as a player, they pick up different skills and things they've learned from being 10+ years pro. They eventually become vets and pick on the younger players still developing as that's when they're most vulnerable.
It's like TD vs Griffin & Cousins years ago, or Gay & KD vs Leonard. TD owned them when they were young, but not anymore, same with Gay & KD owning a young Leonard.
