Has Ngannou put the notion to bed that different sports yet similar do not mix? Can a world champion squash player with an elite camp be competitive against a world champion tennis player? Look how good YouTubers Jake Paul and KSI are doing with the best trainers.
The only thing Ngannnou put to bed is Fury being anywhere close to being an ATG except among members of his cult
What was witnessed with Fury/Ngannou was a perfect storm of shenanigans. A fat sloppy semi retired over the hill HW that doesn't have the power to threaten someone unless he's in shape and can beat on the other person over multiple rounds and that didn't take a fight seriously against a freak of nature. Ngannou would've struggled with damn near any HW in the top 20 that actually trained..............and that can hit. Fury would've lost to probably 7 of the top 10 on that night (probably gotten stopped by 3-4 of em)
