As someone who has been in the ring, a 10 lb. weight advantage doesnt mean jack shit. Depending on the distance of the reach(Lewis/Tyson fight),that may or may not make a difference in a fight.

What I dont get is why does a boxer get flack for quitting?
If your losing and you know it or are in serious danger,why cant you quit gracefully. In MMA,we can tapout without being labled a quitter.The safety of the fighters is important. We risk broken limbs and permanent injury,every single time we fight. Brazillian jujitsu legend,Mario Sperry once said "Its better to be a dog and live to fight another day,than to be a lion and fight no more."
