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.

You're saying that his bunk that if you don't push into the floor and turn or pivot the foot there won't be any power.
