Are we talking super-prime, ultra-focused, best-of-the-line Audley Harrison or are we talking the regular version?
This a mismatch Harrison didn't even prove he was above British level going life and death with the likes of Sprott, Rogan. In his prime he tried to step up vs Dominick Guinn who was a solid top 15 Heavyweight and he got beaten comprehensively. Golota would dismantle Harrison.
Harrison easily. All he would have to do is let his knackers slip out of his shorts and Golota would be unable to resist punching them up into his throat.
