Despite some boxers doing so with ease, going up in weight is usually a tough thing to pull off, making that decision more difficult.
Guys like Floyd Mayweather and Manny Pacquiao seem to jump back and forth between weight classes nearly every other fight. Most fighters gradually move up the scales as they get older, add more muscle to their frame and decide that they don't want to go through the hassle of trying to cut down to a lighter weight anymore.
Of course, there are times when that decision is made too quickly for a fighter, and he ends up not prepared for the power he'll see at the next level. That's what happened to Adrien Broner against Marcos Maidana last December.
As I mentioned before, Pacquiao has moved up in weight throughout his entire career. Could he move up again and claim a world title in a ninth weight division?
I would say that the answer is 90 percent no because both he and Miguel Cotto share the same trainer, but it's possible. Fighting at 160 pounds sounds crazy initially for Pacquiao, who won his first title in the flyweight division, but he and Cotto have fought before, so I don't think the weight would be an issue.
While the bout would be for the 160-pound title that Cotto won from Sergio Martinez last month, neither fighter would likely weigh in right at the limit. Cotto is the naturally bigger man, but it wasn't a problem for Pacquiao when he stopped Cotto in the 12th round of their fight in 2009 at a catchweight of 145 pounds.
As long as Freddie Roach is the trainer for both guys, the fight won't happen. I have a hard time imagining either fighter leaving Roach, but the rematch makes sense for both fighters.
There are some intriguing options out there for Cotto—especially if Top Rank and Golden Boy start working together as promised—but what potential Pacquiao opponents excite you?
I have zero interest in a third fight with Timothy Bradley, Ruslan Provodnikov is likely off the table since they share the same trainer, and Pac-Man would wipe the floor with Mike Alvarado or Chris Algieri. The only fight I'm interested in is a fifth bout with Juan Manuel Marquez.
Other than that, not much excites me, and Pacquiao still has five fights left on his contract with Top Rank. The problem is that most of boxing's exciting fighters at 140 and 147 are signed with Golden Boy or Al Haymon. Every Pacquiao fight will be on HBO pay-per-view so one of the fighters on the other side would have to cross over, which is doubtful.
In all likelihood a second fight between Pacquiao and Cotto won't happen, but there are many other star fighters who should consider a move up in weight. My criteria for who should move up in weight will be determined by the quality of the division, the money that could be made in another division and whether they've simply outgrown their current weight class.
I'll go over a few of those names over the upcoming slides.
