Talking about a Golota that doesn't implode is like discussing a Terry Norris with an iron chin, or a Haney with power. It doesn't exist, so no sense dwelling on it.
For the sake of argument, even IFFFFFFF Golota was mentally strong, he still didn't have the tools to beat Tyson. He was too stiff and straight up, and more importantly, he never knew how to clinch when hurt or to blunt an attack. So even if you take Golota at his absolute apex and bless him with mental strength, and you match him with any version of a prime Tyson, Mike still wins 10/10.
Plus Golota was very intimidated by Tyson Probably grew up watching him... as he didn't seem at all intimidated by Bowe
