who took the more serious challenge, mayweather or pacquiao

[Kagami Taiga]

shane is by far the toughest opponent either of them have ever faced.

[2501]

Pac - Cotto

Floyd - Marquez

this.....

Remember, it was going to be Mayweater/Malignaggi if it wasn't for Haiti.

[madsweeney]

We'll see if. If we get the Mosley that KO'ed Marg then FLoyd gets it. But if we see a 40 year old man chasing Floyd on a walker...well...
