Floyd Mayweather, Possibly Signing with UFC?

Floyd Mayweather has been rumored to be Dana White's big news. There has been much talk about Anderson Silva moving to light heavyweight to fight Chuck Liddel, but a source close to Mayweather states that they have been talking to Dana White about possibly signing with the UFC. Floyd is an elite athlete and If he really jumps into MMA i think he would be unstoppable. It will probably take a year or more to get a well-versed game, but none the less he would be a good addition to the UFC. Do you think he's good for MMA or should we hope this doesn't take place at all?
