Why would Marquez be a more viable opponent than Mosley for Manny?

[ono]

Mosley has had one good performance in the last 6-7 years.

Do you watch boxing? Cotto, Collazo, Vargas II, Margarito. He would have had more, but there were long stretches where he was trying to get big fights.

He was just ok against Cotto though. He looked good against a finished Vargas and Collazo broke his hand in the 2nd round of the fight with Mosley, after initially looking very good.

The only really good performance came against Margarito.

He was poor against Mayorga, Estrada, Cruz, 1st Vargas fight, Mayweather (apart from that punch in the 2nd) and finally against Mora.

He quite clearly doesn't have enough in the tank to deal with Pacquiao's movements as the fight goes on. He was clearly gassed against floyd. Against Pacquiao it would be much worse as he would have to fight at a higher tempo. I think it would be a terrible fight in all honesty. Wouldn't even be remotely close.

Marquez - Pacquiao is much more interesting.
