Floyd has more skill but Punch has 100lbs on him. Who would win

Hi, I’m a retard.
I think that’s a bad comparison because a 95lb person is simply incapable of inflicting any real damage. However I’m sure you even at 180 would be able to make a 265lb dude feel pain (assuming you workout and have a bit of fighting skill).Boxing match, Floyd wins as long as he avoids any major shots. He'd be dancing all day. Win on points.
Street fight/MMA, Kimbo wins. Weight difference matters a lot. I weigh 180 lbs. Pair me up with a really talented 95 lb breh.....he might land some hard shots with those bony knuckles but I can walk him down and just sit on him.
