How many boxers have cheated in their weight since the dawn of catchweights?

The concept of the catch weight as we know it now is a sham itself. There's no comparison with the old catch weight practice of the earlier times because then the weigh in was held on the day of the fight. Then also the smaller fighters did not force their bigger foes to drain. Today only the bigger foes are forced to drain to meet the supposed common catch weight while no sanction is imposed upon the smaller fighter who failed to bulk up to meet the supposed common catch weight.The essence of the catch weight is to equalize the disadvantage of reducing weight ( for the bigger fighter ) with the disadvantage of gaining weight ( for the smaller fighter ).

Pacquiao has failed to meet the supposed common catch weight at least twice ( vs. Oscar at 147 and Margarito at 150 ). Floyd just fought one catch weight bout versus JMM and he came in at least three pounds over the stipulated 144 lbs. limit and had to pay the fine. The catch weight in Armstrong's time was different in that only Armstrong asked that he be allowed to just come within the weight limit of the higher weight division he was fighting on while he did not require his foes to come in below their comfortable weight as long as they did not exceed the division limit.

When the WBC ordered then middleweight (160 lbs.) champ Sugar Leonard and then light-heavyweight (175 lbs.) champ Donnie Lalonde to fight for its newly created super middleweight ( 168 lbs.) championship, the agreed common weight was 167.5 lbs. At least Sugar tried to meet the weight and even resorted to cheating to officially make it during the weigh in. Lalonde had to shed weight to make the limit and as a result, he faded badly in the middle rounds and was kayoed. The camp of Leonard later admitted that Ray just actually weighed a little over 162 lbs. The rest of the weight were attributed to metals sewn inside the hem of Sugar Ray's trunks.

Fighters cheat weight all the time that's why the don't have same day weigh ins anymore so more fighters can actually shave down and make the weight.

Now, of course Manny and Floyd are the two names everyone is going to point to,but you have to understand that they were the first nor the last to manipulate weight classes and they won't be the last.

That is not cheating, most boxers will fight heavier than their record weight, which is taken 24 hours before the fight.

You can always be less than the weight limit, but not over the limit at the official weigh in.

Almost everyone does not weigh the same at fight time as they did at weigh in.

Floyd Joy Mayweather Jr. is a catchweight cheat.

why dont you fill the tub, plug and toss the toaster, and dive.

If you survive, bang your brainless head on a brick wall and give us all a favor.

Thanks
