Any of Micky Ward's big fights were won from going to the body first. That "head-body" double left hook was his trademark. If you haven't watched Ward-Green, find that one. I'm not sure anybody else used the body shot as a finishing blow the way Micky did.
Danny, more fighters don't go to the body for a few reasons. Body punches don't score as well with judges as flashy headshots and the benefits of body punching pay off more as a fight goes on. In the short amateur and entry level pro fights, a sustained body attack is less likely to pay off "money in the bank." Only fighters who are excellent body punchers find it worth it to go the body in those fights.
The other reason is that when you go to the body you leave yourself open to big punches - like nasty right uppercuts. If you have a sub-par left hook, the risk-reward is tough and straight rights to the body are also a risky proposition. If you are a shorter fighter, you have no choice but to develop a body attack, but naturally long and lanky fighters can go pretty far with an attack that doesn't include much body work.
