True or false most pro boxers dont pivot the foot they push off it?

Hip cannot move on its own as i mentioned, in another thread impossible only 6 degrees lateral up or side. Otherwise you would damage the coxxys, thats the reason, so there something else moving below it.

What do u you see here?

I see Tyson not moving his feet at all, and still torquing his hips a fair bit and not damaging anything other than his opponents head.
