Floyd Mayweather Jr Thinking of Competing in Mixed Martial Arts?

Floyd Mayweather Jr has reportedly been considering a move into MMA after having beaten most of the fighters at or around his weight in boxing. Whether this idea will ever come into fruition still remains to be seen, although it would certainly draw fans from both sports to see how it played out. Many people have stated that this might simply be nothing more than hot air from Floyd, who is seemingly looking for his next challenge after publicly retiring from boxing again.

One thing that might be holding Mayweather back from actually moving into MMA is that he would likely have to take a significant pay cut for doing so. While the fights he might be involved with will likely generate similar amounts of money in terms of viewers and sponsors, mixed martial artists get a much smaller percentage of the total than boxers do. Although he will be able to command decent money, perhaps even millions, it will likely be a lot of risk for little reward when he can make more money more easily through a few more boxing matches.

Should he decide to ever enter the Octagon, could he truly handle a loss, and  his 39-0 record be shatterd?  

He has a professional boxing record of 39-0.  When/if he makes a transition into MMA he'd have an official MMA record of 0-0.  Thus, leaving his undefeated boxing record intact.
