Former world champion Paulie Malignaggi is wondering why boxing fans are still calling for a showdown between Floyd Mayweather Jr. and Manny Pacquiao, saying that the super fight might turn out as a lopsided bout.

In an interview with On The Ropes Boxing Radio, Malignaggi said that Mayweather will be too much for Pacquiao, pointing out that the Filipino boxing icon doesn't have a chance to hand the pound-for-pound king the first defeat of his illustrious boxing career.

Malignaggi said that Pacquiao is not as explosive as he was before and that most fans are just holding on to the fact that the reigning World Boxing Organization welterweight champion was once considered as the most dominant fighter in the world.

"He just doesn't look as explosive to me anymore," Malignaggi said of Pacquiao. "The Pacquiao hype train is based really on about two or three years of his career, it's nothing based on before then and there's nothing based on after that because nothing before or after that was very impressive about Pacquiao. It's based on about a two or three year run Manny Pacquiao had where he looked like Superman. I think everybody is holding on to that."

Malignaggi, the former World Boxing Association welterweight champion, conceded, though, that big-money fight between Mayweather and Pacquiao could still happen.

But if given the chance to pick Mayweather's next opponent, Malignaggi said that he'd rather choose Keith Thurman or Amir Khan instead of Pacquiao. He said that Thurman and Khan are bigger threats to Mayweather, while also adding that both fighters also have the tools to win against Pacquiao.

"Personally I think if you really know your boxing, you're not really that excited about that fight, but I think guys like Thurman and Khan in my opinion have a real shot at beating Floyd Mayweather," Malignaggi said. "They would also probably beat Manny Pacquiao as well. At this point we're in 2014 going into 2015, I think those two fighters especially have a shot at probably beating both guys, more than likely."
