so much ignorance in a thread...
First off anyone can get knocked the fukk out, no such thing as a superman....
In saying that Mayweather would beat 50 within an inch of his life....
Ive said it before Ive been boxing for 22 years since I was a kid.... few basics for the uneducated
I can guarantee you that Floyd can hit the punch bag with probably twice as much power as 50 ....
weight is not the determining factor in how hard you punch although it is very important, technique is....If you throw a punch and your legs arent moving and your waist isnt twisting then you havent thrown it correctly....the power comes from your legs ... generally boxers have lean muscle mass, big biceps add more weight and make the punches heavier but the power in a punch comes from the legs and technique, conversely the bigger your muscles are the more it will affect your stamina and speed which is why old school boxing trainers prefer boxers not to train with weights too heavy...
Even If an amateur boxer is going to the gym twice a week hes throwing between 2000 - 3000 punches minimum ......how many punches you thrown in a year? really
As a boxer you see things untrained people cant, all the fights Ive seen on worldstar only two people looked decent, the security guard fighting the dread and the bus drivers upercut, other than that street guys cant fight...
I dont see people blocking punches, slipping punches, ducking, parrying....stance is wrong all off balance, chin up in the air,zero head movement, hands too low down...
only novices talk about "chins"... I would rather be hit in the face 10 times than take a hit to the body, a punch to the chin will knock you out but a punch to the body will leave you in devastating pain, do you know how hard it is too hit a trained fighter in the face?
boxers are taught always to be slightly out of range of their opponent and never square on, when you punch someone you are supposed to step in and step out before he can counter, with street cats you can do this all day till you get bored of hitting them
brolic street guys come into the gym all the time and even though you tell them they arent ready they want to spar, so we put them in with a 14 year old white kid and they get the brakes beat off of them, thats when they become humble and respect what we do..
A trained boxer is fast , very fast, a trained boxer knows when you are going to throw a punch before you do, a trained boxer knows which hand you are going to punch with, a trained boxer can set traps to make you throw a punch and when you do you will hit nothing but air and believe me you wont even see his punch coming you will just feel it
me personally Im a defensive fighter, Im a counter puncher, I more or less use the Philly shell defense so Im quite comfortable with having punches thrown at me
like I said at the beginning anyone can get knocked out no one is unbeatable, but anyone who thinks because they are big and have been in a few streetfights they can handle a trained fighter is deceiving themselves
And no, for the record I also doubt 50 is gonna hit Floyd with a clean punch, IF he can hit him at all. I just don't think Floyd would cause so much damage that 50 to the hospital within 1 round, and b/c of that nikkaz is all crazy and sh*t
You actin' like 50 gon' get in the ring, take one shot, and go to the hospital. Again, you nikkaz hype up these athletes too much. We are talking about a 50 lb muscle advantage. Unless 50's jaw is made of the same materials as Ace Hood's watch, he would be ok. F*ckin' Tyson got into street fights with citizens, and didn't knock 'em out, and somehow Floyd is going to send a 220 lb guy to the grave 
face for the rest of your life
