Thing about your logic there is that Froch was dropped and hurt by Taylor who also came up from Middle. AA hits harder then Taylor.
I don't think Froch was hurt by Taylor when Taylor knockdown Froch. When Froch got up, he look fine and relax imo.
The thing is i knew Abraham was never going to win this fight. And when taylor put froch down he got straight up and went back to buisness...
