I see Broner do it a lot and Floyd often on the Heavybag.
They simply slap instead of actually punching.
Why is that? Why would you wanna slap instead of punching for real especially on the hooks.

For speed not power, and you also don't want to be damaging your hands if you have a fight coming up.

But mostly showing off or they like the sound of it ha
