I don't understand why some people don't want to see a champion unify all the titles in his division. Boxing fans should cheer for this. Boxing needs fighters like Golovkin. He's trying to achieve greatness in his era like Hopkins and Taylor. Most fighters in these days are cherrypicking their opponents and milking a paper title. Golovkin and Kovalev want to be undisputed champions.
GGG so far is the best boxer in terms of craving a historic legacy for himself, so far he already broke a long standing record: 15-0-0-0 (KO 15) consecutive 100% KO ratio title fights (GGG 2016) [*]14-0-0-0 (KO 14) consecutive 100% KO ratio title fights (Gomez 1980)
