Yes, but how does training help a knocked out fighter when he receives 3-4 more uncontested blows to his face? Is it because their head is already flat on the mat, and is absorbing less impact from the punches or something?
How are combat sports a thing? I've seen so many MMA fights end with a dude getting knocked out then the winner wailing on his lifeless face a few extra times before the ref pulls him off.
