Why do people always make the mistake of assuming ground fighting = grappling. Striking whilst on the ground is also ground fighting.
because the two are connected deeply. You have to know the inner workings of ground work to be able to get leverage. The ability to strike with any kind of meaning on the ground is rooted in leverage. If someone knows how to "lock down" someone to where they cannot get seperation then your ability to "ground fight" is null and void. So grappling in itself is the basics of being able to ground fight, because it teaches postioning and movement which in turn give the ability to "ground fight" Why do you think most wrestlers and such are good at Ground and pound? Because they have advantage in being able to dictate the directions and movements on the ground in order to obtain that ability.
