As far as Jeff Mayweather, Floyd Mayweather Jr.'s uncle, is concerned, the May 2 fight against Pacquiao was nowhere near the level when Floyd Jr. faced off against Marcos Maidana.

Speaking in an interview at On The Ropes Boxing Radio, Jeff Mayweather singled out Maidana's stand on his nephew as highly competitive compared to the May 2 fight where Floyd Jr. won via unanimous decision.

It will be recalled that despite his lack of aggression, which most boxing critics are hitting, it was a fact that Mayweather Jr. dictated the fight and practically walked his way to the 12th round.

Of course, there was that controversial shoulder injury that Pacquiao's camp sounded off after the fight, something which practically explained why the Filipino boxer threw few punches than normal.

That aside, Jeff Mayweather credits two fighters for giving his nephew a challenge – Marcos Maidana and Miguel Cotto.

Maidana, as everyone knows, fought Mayweather twice. The first time came on May 3, 2014, a tightly contested match, which many believe was the closest any fighter could have of possibly pulling out an upset. And with that in the air, a second fight was made several months after, on Sept. 13, 2014.

This time however, it was a different story. Maidana got schooled this time as Mayweather obviously did his homework on the Argentine boxer.

"There are other fighters that have done better, not just Maidana. Maidana did real well in the first fight, but he didn't do as well as people thought either. The one thing is this, Floyd dominates fights so easy, that any time a guy wins three or four rounds, they say he lost, which is ridiculous," says Jeff Mayweather in the interview.

With regards to Miguel Cotto, the Puerto Rican showed his toughness against Mayweather although the outcome still stood in favor of the flamboyant one. Mayweather won via unanimous decision on their May 5, 2012 tiff.

 As far as Pacquiao is concerned, J. Mayweather doesn't buy the reasoning that the Filipino boxer's poor performance was due to his injured shoulder.

"First of all, every fight that Pacquiao's had, when he had the calf thing — and most people know where that comes from — that's the first thing to come out of his mouth. You got a torn rotator cuff and you're not gonna complain once in the entire fight? When you have a torn rotator cuff, you can't even rotate your shoulder, you can't do nothing. It was just a way to come up with a damn excuse hoping that he could sell that to the people and get a rematch," he says.
