That is a ridiculous way to compare the level of athletes. An olympic wreslter would destroy a pro boxer. If you can’t grapple you can’t fight. It’s as simple as that. Just because you don’t understand the ground game doesn’t mean it isn’t a great way to fight. Fighters don’t choose to grapple because they can’t punch, they grapple because it is a more effective way to fight one on one. I bet most pro boxers don’t have what it takes to be a champion wreslter.
