Aaaah,good points Mr.Wacko but I put to you that even without Arum,there are alot of factors in the way of the fight:

Mayweather wants too much

I think Oscar would rather fight Tito.

Oscar does not want to be a stepping stone to anyone,his ego would not allow it and remember,he does not need Mayweather.

Didn't Floyd's pops say he would never train a fighter to fight his son?

and from fans perspective,does fighting Oscar gain Floyd more credit? Not in my opinion unless Oscar some how magically tunrs back the clock and puts in an awesome Old style Oscar performance which is highly highly unlikely.
