Are the Diaz brothers punch drunk? I watched a Nate Diaz interview and his speech is slow and slurred. Is this the case? Diaz is so tough he can take kicks and punches that would normally knock a human being out. But consequently his incredible chin has allowed him to take more hard blows to the head. The punches Conor McGregor landed on him would have knocked out almost anyone. So is Nate Diaz punch drunk?
