Prior to reading what Wilder said, I would've given him a fighting chance against anyone else besides Tyson Fury. It's not like Deontay fought no one but bums leading up to Fury.
I still maintain that Wilder has progressed enough to beat 95% of the HW's out there.

But reading about him saying he's "accomplished everything there is to do in boxing" and hinting about retirement makes it a different ballgame altogether.
Anytime a fighter says this after devastating losses, it hints at a loss of heart and desire.
If Wilder is going to go forward thinking he's got nothing to learn and nothing to atone for... or even something more to achieve.... he may as well hang them up now for sure.

With less than a 100% percent mentality... and if Ruiz lays off the burritos and gets back to "1st AJ fight" form... Wilder may as well suffer another devastating KO loss... and then for sure he should hang them up.
