question my friend.

My opinion is Floyd did that act not because he had been butted, but rather because Ortiz came hard at him on the ropes twice during that round. The second time, Floyd went back into the ropes because Ortiz was landing/partially landing punches and Floyd couldn't use his legs to out of harm's way. It wasn't a case of Ortiz actually pushing him into the ropes (rather punches landed/block forced him back).

It wasn't the strange situation we saw with De La Hoya with Oscar flailing his arms but not landing anything with Floyd on the ropes. Ortiz landed some of his shots and there was actual danger for Floyd.

All that said, I think Floyd would have outboxed/stopped Ortiz with right hands later in the fight, but my opinion is still the same, Floyd took that shot out of fear.
