Mosley is going to have an extremely hard time winning this fight, he isn't great at dealing with movement, he doesn't throw straights punches(jabs and crosses) as effectively as Mayweather, and though he has a much harder left hook, it doesn't land as accurately from the outside.

After watching Mosley-ODLH 2, I can't see how he won that fihgt, but also how movement, but not running really caused him a ton of problems, and how a great jabber can easily outjab him, if movement is incorporated.

I just see Mayweather's in and out movement and defensive skills as too profound for MOsley to beat, I think he will really frustrate Mosley because he won't be there to be hit in return as quick as Mosley is.

The only chance Mosley has is muscling Floyd to the ropes a lot like Castillo and Oscar did.
