You honestly don't sound convinced a guy should retire until he's either dead or brain dead tbh. Bernard Hopkins is the boy who cried wolf then. He pulled stunts against Cazaghe and even Roy Jones early in their fight.
Hopkins has pulled stunts throughout his career... it's what he does. He's experienced and smart enough to know what you can and can't get away with and when you can and can't do it. If you give him an opportunity he'll take advantage of it.
No-one liked the ending of Hopkins/Dawson just like no-one liked the way he flopped around every tie Roy Jones touched the back of his head in the rematch. None of that means he shouldn't still compete.
While you make great points with others, I think the Holyfield one is way off, the reason I say that is because you seem convinced a guy isn't done if there is still a level of competition he can fight.
Thats like if Bret Favre couldn't cut it in the NFL anymore, but he went to Arena league and he was alright there, but isn't even the best in the Arena league anymore. "Yeah but he still went 7-4 with a winning record in arena league"
And why is that wrong? If a guy still wants to compete, wants/needs the money and is still able to compete at some level then why should he retire? Because
you don't want to see him at that level
I'm sorry that you have a sense of entitlement that means that fighters should retire when you want them to or as soon as they can't face the sort of opponents you want them to. Let us be clear... we're not talking about a
63 year old Ken Buchanan, riddled with drink problems, who hasn't boxed in 20+ years wanting to make a comeback... we're talking about a 49 year old man who has kept himself in as good shape as he possibly could, has gone 6-2-1 in his comeback and has never been beaten up... and only clearly beaten once. More, we're talking about a guy who picks his opponents well... the likewise old and faded Botha, Savarese and Nielsen, the limited (and no spring chicken) Maddalone, Oquendo and Williams and even in his world title bouts the likes of Valuev and Ibragimov. He's not putting himself in with killers, he's not facing the best... he's facing opponents he can (and does) beat fairly comfortably with limited risk.
Evander Holyfield has pretty severe financial problems. Despite his best efforts the only way he's been able to make money is by stepping into the ring. You may like to see him pennyless and broken-hearted having lost the thing he loves, another sad tale of a boxer lost but me, personally, I think he should be allowed to make money the way he knows best, facing opponents he offer him limited risk. He's not getting stopped, he's not getting rocked, he's not even taking many punches... there is no reason other the fact that
you only want to see him at the top of his game for him to not keep boxing at this level.
