I guess there's two schools of thought.

There are those who insist that fighters move up in weight to be considered "taking on challenges."

Then there are others who feel a fighter should fight in the weight he is comfortable in. If the fighter doesn't feel he can carry his power or skills to a higher weight... so be it.

There are more than a few fighters who have fought practically their entire careers in one division, or have reached a ceiling beyond which they choose not to move up.

Hagler being one. GGG being another. Of course, GGG allowed himself to get dragged to 168 at 40 years old (for the money), so he could get his ass kicked by a much younger, natural 168-pounder. But most of his career, he was a middleweight.

Now... there are the Pacquiao's of the world. I admire Pacquiao very much. He went up through several weight divisions, and was successful. Of course, there are those who suspect PEDs... but that's another story.

To those who can move up 2 or 3 divisions and be successful... good for them.

I was a HUGE Trinidad fan... and he moved from 147 to 154, and even won a championship at 160 before being beaten by an ATG middleweight in Hopkins.

Cotto was SUPER at 140, 147... won at 154... but I always thought his try to be successful at 160 was a bridge too far. At some point your body doesn't carry the weight and the power.

So basically it's all a matter of tastes.

I admire the guys who can traverse through 2 or 3 division. But I also admire the guys who are mega dominant in one weight division year in and year out.
