A few in the Heavyweight division at least that can think of .. Foreman V Lyle Norton v Holmes Moorer V Cooper Cooper V Mercer And short but sweet ..Dempsey V Firpo.
Maybe I'm out of the loop here, but what is a two sided fight? I think I know, but to me it could either mean the most evenly contested, competitive fight imaginable throughout, or it could mean a fight that was intermittently one sided for one fighter followed by a surge where it veered one sidedly in the other direction. In term of evenly contested, Barrera-Morales I & III were the height of deadlocked trench warfare. But in terms of a fight that was at times one sided for both men, I'd point out Corrales vs Freitas, where 'Popo' was winning in dominant fashion until he faded and Corrales surged, beating him down violently for the last three.
