It's not about who has the best wins, though. It's about what fight makes more sense and means more to Mayweather's legacy.

Floyd beats Khan... so what? He's been beaten 3 times by guys not even close to being in Floyd's league. Even if Floyd knocked Khan out in 30 seconds, it'd be "so what, Khan has no chin".

Brook is a 10 year veteran with an undefeated record and a win over one of the best WW's and he's currently Ring magazine's #1 WW behind champ Mayweather.
