Wlad wrecked prime Pulev with the few poweshots he landed and that Pulev is looooooooooong gone. I'd be surprised if Pulev makes it past 5 & if he does it's only because AJ is playing it extremely safe.
Doug Jones didn't knock Ali down. Banks, Cooper, Frazier and (officially) Wepner (but he stepped on Ali's foot).
It does? Ali was actually dropped three times in 61 fights. Joshua has been down five times in 24 fights. What point did he make, exactly? Going down five times in 24 fights ISN'T good.
Fighters change,styles change,ability changes. Recuperative power matters aswell. Guys like Bobo Olson went down and never got up while guys like Marquez always got up. Nuances.
