Most likely Golota chokes up again in a big event and when Headbutter notices that he is scared shitless, he takes care of business pretty quickly. If Golota was able to hold himself together he might even win, but that was never going to happen
Holyfield by DQ round 8. Golota would in fact outbox him I would say after 7 rounds it would be 5-2 Golota but Holyfield's heart, chin and skill and will and on top of that Holyfield's headbutts would piss Golota off and make him quit mentally just like in the Tyson fight.
Don't like picking DQs in mythical fights (even when it's Golota) so give me the safe Holyfield mid to late pick.
Funny thing about being emotionally weak. I bet if you told him Holyfield's record was 6-10 and never showed him any footage of him, had the fight staged in some school gym with 100 people watching he probablly beats him up but put him in front of millions tell him Holyfield is a legend and he folds.
