It's extra funny because Ali and Haye are pretty equal in dimensions and Haye is one of the shittiest finishers there is at high level.
He couldn't even finish Fraudley that effectively.
Haye his only 3 "true" KO wins comes from a blown up lhw bum, a cruiser bum and Alexander Gurov who had been KO'd in 1 before and is a glass jaw.
Haye would get stopped against Ali.
Even if Haye scored a lucky flush hit, Ali would just tie him up.
