Little big men fighting large heavyweights? Apparently tank Davis is gonna fight Jake Paul. 140 vs 190+ And also Mayweather vs Tyson will happen. 147 vs 225. So, on that thought pattern what would happen mythologically if Manny Pacquiao fought a rocky Marciano? So 147 vs 185ish. There is some method to this madness: PAC was agile, used depth perception tactics, took on many more naturally bigger fighters. WHILE rocky was a small hw by today's standards and if I am correct he used to bleed a lot and had 2 left feet while dancing meaning poor or sluggish footwork. I know this is gonna generate a lot of mayhem, but it's just a trivial just for the heck of it!
The only reason Tyson-Mayweather is semi reasonable is because Tyson is a pensioner who has been shot to pieces for 20 years plus and got owned by Jake Paul who Mayweather beat easily. Pacman vs Marciano isn't completely crazy as a match up because Pac's range and height isn't much lower and he's infitely faster. But on the way in he'd get timed with big punches and on the inside he'd get destroyed. If Marciano pushes him back Pacman can not really fight on the back foot.
Actually, Dwayne has notably dropped quite a bit of weight/bulk in more recent times. Perhaps a hint of an upcoming catch weight fight vs the current version of Manny with Rock falling in to the DLH weight drain trap. Prepare for death by a thousand needles/cuts.
