Does Pacquiao depend too much on athletic abilities to win??

he doesn't depends too much on athletic ability but regardless of that if his body is starting to break down on him then he could have a short period ahead of him.

These leg problems seem to be something serious

 

Yes.

 

Yes.

He has unreal foot speed and hand speed. His speed is what kills everything else. He is sort of like RJ in that regard. But if you have it, might as well use it. But it doesn't seem like he'll be hanging around long enough to experience a decline in speed and come back down to Earth.

 

I don't think speed (at least not hand speed) will decline too much with age.. reflexes will though. if he hadn't fought since he was 16 i could see him doing well up into his 30's.
