Manny are betting younger fighters, I am afraid instead they will shine, Manny will only destroy their career.
Agreed, I believe that in order for a boxer to be a champion in each devision requires an experience , it can only be happen if they are fight in many boxer , and gain their endurance, their strategies, and all of a boxer that needed to have, it is needed to be an experienced fighter, Manny needed a Fighter not only a boxer. And yes, Manny can only destroy the early careers of young boxers.
There's a big difference comparing the two fights.
Manny vs Conor here : Manny does not say a word yet, so Conor is waiting for his answer if he will fight him.
Manny vs Mayweather : Manny like the rematch but Mayweather seems not willing to give him a chance.
I doubt that Mayweather will fight again with Manny, he dont want to lose, his statistics matters to him, even though he play some dirty tricks, he always running inside the ring, many people don't like him, but it doesn't matter to him, because what matters is his stats that make him and his game a hundred million dollar game.
