Top Rank's CEO Bob Arum doesn't see a third fight taking place between Manny Pacquiao and Juan Manuel Marquez. He doesn't view money as the real problem. The problem Arum predicts will have to do with weight. Manny Pacquiao has been fighting at welterweight since 2008. Marquez has been fighting at lightweight and below for a nearly his entire career. He blew up to welterweight for a bout with Floyd Mayweather Jr. in 2008 and was beaten soundly for twelve rounds. After the Mayweather loss he returned to lightweight.
Arum thinks the fight at 147 is a mismatch. Many experts have agreed with Arum's position. Marquez has asked Pacquiao to meet him in the middle around 142-143. There is no reason for the champion, who brings the money, to agree to the challenger's demands.
"A fight with Marquez is not possible. It's a question of weight. Pacquiao rose in weight and continued to fight between welterweight and super welterweight and you know the results. Marquez can not go to that weight  because his fights above 135 have not been consistent. You can't have a yo-yo diet where you go up and down. You have to establish yourself in a division and then fight at the weight. It's what Manny did," Arum said.
Arum has the same opinion about a future fight between Mexican rivals Julio Cesar Chavez Jr. and Saul "Canelo" Alvarez. Chavez is competing at middleweight and could go higher in the near future. Alvarez is usually fighting at 150 and wants to win a title at welterweight. Arum thinks the size difference will always keep them apart. Alvarez is a small junior middleweight. Although listed at 5'9, Alvarez appears shorter. Chavez is listed at 6'0 and he appears to be 6'2 or 6'3.
"It's the same situation like Pacquiao-Marquez. It's a matter of physical size. Chavez Jr. is a fighter who is taller than six feet and he will always fight at 160 pounds, and Canelo is small for 147 or 154. That fight is not possible," Arum said.
