He wouldn't fight in Texas for the Pacquiao fight, where they would've sold out the Cowboys' stadium. He isn't going overseas and fight in hostile territory. At this point, it's easier to get Andre Ward to leave Oakland than it is to get Mayweather away from the MGM Grand.
Guy after he beats Manny he should fight any two guys he wants and go be prosperous in his retirement as a boxer and start a full time promoters career.
It would be really pathetic if he fought a c/b level fighter three times let alone twice already. Did the OP give this any thought?
Wait wait wait, so Cuenca is 47-0 and only 2 KO's? Looking at his stats, 98% of his fights have been with other Argentine and all his fights have been in Argentina. Yeah, I don't think he'll get a shot a Mayweather any time soon...
