No, I have seen over the years that fans have this obsession with trying to be the "one" to publicly state a fighter should retire, like they should have any say in this whatsoever. While I might agree that the game has passed some of those fighters you mentioned by, I don't know how it's ever our place to call for them to pack it in and move on with their lives.
It's rarely out of concern for a fighter's well-being, and instead feels more like they want to be the first one to say it and then if that fighter does retire, then what? They say they're right and celebrate? This is a fighter's livelihood, many fighters that retire have little else after it's all over. If we are simultaneously obsessed with fighter pay, shouldn't we be rooting for longtime fighters to cash in on more paydays while they still can? Cowboy makes about $300k a fight I think, and he also owns and operates a ranch to host fighters at his own expense to give them life skills and training. The longer he fights, the more he can contribute to the community, so I say he should keep doing it as long as he wants.
