In terms of game changing, maybe Shaq? The 2004 Pistons? Guys who lead to rule changes, more or less.
Shaq was a dominant force, but was Wilt a dominant force before him. Shaq isn't even in my top-10 GOAT.
2004 Pistons didn't change anything, in fact they were an exception. No team has ever won since without a superstar or two.
Yeah I was going forward from Jordan re: Shaq. The pistons are there because they very literally lead to rule changes, which would imply an impact on the court per my understanding of your definition.
