Also, let's not forget that as well as totally quitting 100%, duran was dirty as f**k when things weren't going his way. In his fight with ken buchanan, he continually threw low blows from the 1st round onwards, but was warned only once for it, in the 12th round! After the bell at the end of the 13th, he hit buchanan low so hard he ruptured one of his testicles and should've been disqualified but they gave him the win!!
Whenever I hear people say 'the four kings' I cringe. Three kings definitely, hagler, leonard and hearns. Duran was a dirty fighter his whole career
