That was terrible scoring. Many times Dirrell hit GGG and didn't get any points for it, whereas GGG was getting points for every punch that landed.
Dirrell should go for revenge in the pros... He can use his flop to the floor style that he's perfected.
2003 in a USA v Kazakhstan tournament in Tunica, Mississipi. Dirrell won 15:14. One of Golovkin's five loses in over 300 fights.
