Or that there are so many teams and so many players that a lot of the stuff that was invented earlier and is considered "patented" by a given player has proliferated throughout the league and become mostly common-place. Jordan's signature turnaround fade wasn't a move he invented, it's just one that he made famous and used more prominently than a lot of other guys, but it was in the league long before him. Hell, WILT was using that every now and again, to say nothing of wing guys. Nique and B King, drafted a few years before MJ each, used that move as the foundation of their 80s wing post game, for example. Bird used it, too. And so many more.
A signature move and a go-to move aren't necessarily the same thing. We think of go-to moves when we think of post players (centers, as you indicated, but post-up 4s and wings/guards, too) and there aren't a ton of good post guys in the league. That leaves most guys taking a screen or otherwise dribble-penetrating to start their possession, so unless someone is rocking the UTEP Two-Step, you're not going to see a ton of really individualized moves.
