Although Floyd is the P4P#1, Hatton is also highly regarded. Therefore it would be a great victory for him but he is not a complete no hoper so it can't be too high up the list. If it were Witter or Rees facing Floyd and they won then the magnitude of the victory would be higher.
??? The magnitude of the victory would be greater if Rees or Witter won? Hatton is probably the Uk's most popular boxer how could the magnitude of victory be any greater if a relative unknown beats Mayweather. I think your confusing the quality of the victory with the odds of an upset. Thats not what we're talking about.
I think you are the one that is confused. When summing up the magnitude of a victory you do not look at how popular someone is. This is not a popularity contest. Instead you have to look at the relative skills of each fighter. The skill gap between Hatton and Mayweather is not that large if we are to believe that Hatton is the best fighter at 147. The gap between Mayweather and the other two fighters I originally named is unquestionably a lot larger so the magnitude on the global boxing world would be larger because the upset would be greater.
The upset would be greater but the magnitude wouldn't be.... If Sharmba Mitchell had of upset Mayweather would that result have reverberated around boxing for a substantial amount of time? The December 8th match is between 2 top class p4p entrants therefore the profile of the match is greater then any other match in boxing therefore the magnitude of 'any' result coming from this contest is more significant then any upset between a top p4p and someone from lower leagues. IMO.
