yup for a few years, Don Curry was awesome, a sensational fighter. He overstayed his welcome at 147, lost to Honeyghan and essentially was never the same fighter again, his confidence was shot and he could not take punches anywhere near as well. It's worth remembering that for 4 rounds, he was beating the heck out of Mike McCallum until one of the greatest hooks of all time ended it.
You might want to look up the word good . If by that you mean, a guy who beat a ton of bums, was outclassed in EVERY major fight he had and whose best win is over a green, china chinned cholo then yes he was good. Personally, I think he couldn't fight at all.
