Was Manny's performance the worst by an ATG?

I say yes. I know styles make fights. But if we're counting fights by guys who'll make the HOF... and are, say, close to past their prime or slightly past their prime... wasn't this performance the worst? I'll say De la Hoya's vs. Pacman was worse. But most everyone ranks Manny considerably higher than Oscar. Duran never looked the way Pacman did last night. Duran was past his prime when he fought a bigger, athletic and hungry Davey Moore and showed why athletic and good are not the same as ATG. Tyson(IMO) looked better vs. Holyfield. Bernard at 50 never put on such a weakass show(you could say, 'What about vs. Kovalev' and I'd say what other fighter took a bigger risk than Bernard that fight, recently? Bernard is not that similar to Manny, I know. But Bhop has fought, I think courageously, past his prime and managed to find other ways of 'doing it' than he did when he was younger vs. Mercado, RJJ, etc. I think other responses to this question could go along the lines of.. 'What about Kosta's last fight? What about Ali vs. Spinks?' I think Kosta is not ranked as highly as Manny(even though Tszyu is a personal favorite) and Ali was older and way more past his prime than Manny is now. Somehow the magnitude of this fight seems to have escaped Manny. It's not just that Manny can only throw to the cranium. It's not just that being undersized caught up to him. He put on a strangely unATG performance and his ATG wins against Morales and Barrera will not be remembered like his moving underwater, sleepy as @#$% performance last night will be remembered. Manny is, basically, tied in greatness to Floyd. But all people will remember is last night's fight.
