Floyd has been a safety first fighter both in the ring and in his choices (for the most part) for 16 years. He's at the end of his time and has noticeably slid. He's on the verge of tying Mariano's record and perhaps overtaking it. He's not going to chose to take a real risk or be concerned with someones 0.

He's in a bit of a quandary though because he will be remembered more for his 49th and perhaps 50th more then anything he did in the past so he may be forced to crap on my theory I suppose.
