Who won the biggest press conference in boxing history?

Floyd nailed it, did you expect something else. Floyd is very comfortable speaking to reporters and the cameras, Manny does OK but he's not speaking his native language or as comfortable in front of the cameras as Floyd.
I liked the respect they gave to each other.
Of course, the high point was when Justin Bieber showed up! Thank goodness he arrived in time for the lineup, I know we were were all worried he wouldn't make it.

Floyd's voice sounded pretty shaky to me. He's lucky no one asked him to read.

Mayweather often sounds a bit wobbly, but he's as cool as a cucumber once that bell starts for round one and that's the important thing. Sometimes people forget how stressful public speaking can be and I don't think it gets any easier just because you are Floyd Mayweather and have lots of money. Mayweather is sometimes a punk and says silly things, but under pressure and in the moment anyone would do the same.
