The combine records of the opposition when they fought them in title fights if they fought them more then once i counted it like they were two people. For Hagler 687-55-11 and for Jones 809-56-13 those are the numbers for that and hear come some more.
Title fights they were in and the results of them Hagler 15 title fights record 13-1-1 and Jones 25 record 21-4.
Most notable wins for both men Hagler's were Duran and Hearns and Jones is Tony and Bernard.
Now numbers are not always the best way to look at things but it helps. When you consider a fight you consider the follow who they beat, how they beat them, were there were in they career when they beat them, size, height, reach, chin, conditioning, heart and also speed and power thats all i got so far. Reason Haggler would when had a chin that was made a titanium, had great power, was relentless and in prime was a god.
Reason for Jones winning was great speed, reflexes, power and also a god in his prime.
So there is some things that you can consider win thinking about fights and need some extra info there you go got some.
Yes Cut i want them separate if you do not mind i want people to read it that way and for everyone i pick Hagler but Jones is a good choice as well.
