It seems these days a fighter is done after losing once or twice. I really think from this point onwards sadly nobody who has ever had a loss will be seen in the same league as Ali Foreman Lewis etc. It's crazy to think Ali lost a lot more than once. Look at how Joshua and Wilder were dis regarded after facing just one loss. Imagine what people would say if Wilder had lost 7 times.
Wilder has been disregarded because it was the first fight he wasn't heavily favoured to win and he took a hiding. For a lot of boxing fans it confirmed their suspicions. Ali had a number of very good wins before losing a competitive fight to Frazier after a several year absence. Joshua fought much better guys than Wilder did much earlier but his hypetrain was derailed by getting bounced off the canvas by an out of shape pudding who then got even more out of shape for the rematch in which Joshua refused to engage with him. It was a smart performance but hardly a heroic showing. This was not Lewis beating the **** out of Rahman to show him who the man really was.
Modern demand from clients looks are undefeated stars. Pro boxing is not like mma, where more matters who you had fought. There are adapded matchups to develop prospects. From first fights with total walking bags till sometimes even matchups like #14 vs #154 for 10 or even 12 rounders. Prospect is more interesting if he does have record like 20-0-0, 20KOs. Matchmaking might help to achieve this.
he had been expected easily to deal with Ortiz but he had problems. Then with supposedly rusty Fury did not managed to win, 2 nd fight he was even worse, Fury pretty opposite, looked that had seriously improved.
Like Michael ''The Bounty'' Hunter he's that rare breed of American fighter who fought everyone and all over the world too. I see a lot of Brit Level Brit Grit in Ali and I think that's a direct result of him sharing a ring with so many Brit Level warriors like Cooper, Bugner, Dunn and London. I think he would have done exactly the same if he was around in this era too because even though he had enormous respect for Brit Level, and rightly so, it's not something he feared which is actually very rare for non-British fighters.
I dont see Ali as the goat. He's not even the best HW. For me joe louis is better than him. Let alone the goat. Your question makes no sense to me.
