I don't even think the human body could do what a small Pac does at 220lbs. If it did happen he'd be some kind of super-Tyson freak.. can you imagine being on the bad end of Pacquiao jackrabbit flurries at 220lbs?
He wouldn't have the same traits as the current version of pac. IF he was 6'3" and 220, and STILL carrying all the same abilities as the Pac we know, he'd be a freak of nature, and likely beat the crap outta them.
Useless is how old babooshka grampa in your avatar would be vs. a 220 lb Pacquiao combo, even at 1/2 speed.
No, this is a very good scenerio & YES, he would KTFO Wlad. Maybe even VK in his old age. And conversely, if Wlad was just another 6'-2", 220lb HW, he'd be miles away from holding a title belt. How would he do it? 1st, he'd have to break free of the death grip Wlad would put on him & then just tap that chin like Sanders did & history repeats itself. :!:
Because South East Asians translate so well to the higher weight classes, right? What if Vitali was a 5'2 super flyweight? Would Angela Merkel still be the Chancellor of Germany?
Of course, 6'3" 220lb ripped, fast, and strong Filipionos are all over the place. They are just too humble to make all the current HW's look the fool and would rather not gloat about how great they are... but they exist... in OP's head.
With improved nutrition available to the population over a few generations I bet there will be someday.
