nonsense is a bit harsh, you are right, it has its purpose

but it doesn't determine who are the best boxers

say the top 30 heavies would beat GGG, considering his size and weight if GGG was to come 30th in HW competition that would be an amazing achievement, but it still only makes him, at the most, 30th best boxer in the world

if there was a under 10 stone rugby league and one team dominated by miles

and there was an over 10 stone rugby league that was a lot closer

that doesn't mean the under 10 stone team is the best team
