atsch Sparring partner for Pascal? I heard he had a hard life. Since amateurs Dirrell and Bute especially worked their asses off. Golovkin is a fraud in professional boxing, you'll see. Professional boxing is made for technical boxers more, less for punchers (roosters). And I didn't ask you about him.
It's the other way around, technical fighters with little power have more success in the amateurs and punchers with little technique have more success in the pros. It's irrelevant though because GGG has both power and technique. Khan would give all his sports cars to have half of Dirrell's skills.
