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

But if you look at the video clip of sugary Leonard he barely moves,his right heel is planted and he doesn't kick out the left heel much.

I'm not trying to be argumentative this is just a discussion

You can very clearly see the heel lift and turn a little, plus the knee moves in. It's subtle, but it's definitely there. Remember you're watching a pro, one of the greats in this case. His movements are gonna be smaller than the ones you learn, his body knows how to move and doesn't need bigger movements to be taught.

Notice how he punches downward its looks more like a shoulder roll in comparison to our coach who turns the thumb in for a level punch.
