When a guy has had his brain repeatedly rattled with heavy punches for 30 minutes, I don't think it is beyond the realms of possibility that he will not be able to think clearly or fully consider the consequences of what he is saying. Just because a badly beaten fighter can still talk post-fight, does not mean that he is OK. I think you have to give Lopez some slack. He most likely doesn't remember much of the fight, nor the minutes after the knockout.
Adding to the physical trauma is the emotional trauma of a confident guy learning what defeat is like.
