Don't know and doubt he will consider a rematch if he got KO'd, if it's a close decision then a rematch is possible though retirement seems more likely at this stage and depending on how he loses.
His whole existance, personality, everyting would change. He would be completely ruined as a man like humty dumpty when he fell off the wall. it would be total devastation which floyd knows he couldn't handle. like how Roy Jones fell apart from the Tarver KO. phloyd learned from that, he will never ever go near fighters who have a good chance to totally destroy him - such as Margarito, Cotto, Mosley and Williams. he would even stage a fake retirement so as to avoid that devastating KO loss
I think he will handle it with the same class and dignity that his father showed after the Hatton loss!
My first thoughts were not that good and that hed ***** and make excuses. But then again i thought thats what Jones would do but he seemed to accept defeat like a man. Maybe we will see on March 13th,but I think we will probably have to wait longer than that cuz im thinking Floyd will decision Pac.
He would handle it the same way as Naseem Hamed handled a comprehensive loss. His mentality would be shattered, irreparably.
