If the heavyweight had both hands tied behind his back ,maybe.
It can go either way . The Flyweight can win on points since he is a lot faster hands and feet wise . The HW punch will do more damage and will knock the Flyweight out with one good punch. As long as the FW plays it safe and doesn't get hit , he can win (but very unlikely. the HW will have a big reach advantage)
Heavyweights r slow and clumsy. A gd fw could win by decision if he has good boxing smarts and decent speed. Look at David Haye and Nikolai Valuev. Haye had too much speed for him and even rocked him later on when Valuev outweighed him by a significant amount
It's possible, but highly unlikely. That's really asking a lot for a person to win a boxing match against a person who outweighs him by at least 100 pounds.
In a game of chess maybe but in a boxing match, come on are you serious? Of course not!
Only if the heavyweight was an accountant.
his punches wont effect the hw, one punch from the hw and the fw is dead
Could the flyweight ever win, having no specific advantage?
