The worst one I saw was a guy was in a toughman contest. A guy who was winning suddenly the fight was stopped and the guy who was winning got the L. I thought he was going to get the W cause he was winning. His opponent got stopped in one the next night.
Pacquiao-Cotto was a bad stoppage? Okay, you sit in with Pacquiao for 12 rounds. You'd jump out the ring after the first punch. Cotto clearly wasn't winning and was recieving pointless punishment. Great stoppage. Could have been stopped well well before.
pac cotto wouldn't have continued for twelve, he would have been starched at some point in that fight better to stop that **** than to let a fighter who has had a lot of tough fights already get beat up uselessly for more rounds
