Fedor fights now for two reasons, and none of them have great concern with win loss records.
Fedor fights now to challenge himself. He goes against his opponents strengths, instead of the usual attacking of their weaknesses. He boxed Maldanado, when Maldanado was a pro boxer. Why? Because he wanted to test his boxing skills. And he got clipped, but showed how much of a warrior he is by surviving and pulling out for at least a draw. Its his choice. He fights his way. In that respect Fedor is now like Nick Diaz was a couple years ago. Nick had no care about what others thought about him. He attacked the the strengths of his opponents, even if he had other ways to win. And when he lost, mostly by decision, he did it with his honor intact. Bushido.
Second, and more importantly, he fights to put his fighters on the card, and give them recognition. Fedor has no glory seeking bone in his body, which a lot of people don't understand. His legacy is set.
