Was it not Emanuel Steward whom said something about that it is good to be able to take a punch, but is not good to take too many? I could not find it in neither DuckDuckGo nor in Youtube. Who knows?
I recall Jones way more saying that. Every few fights when one guy's standing up to heavy shots Jim Lampley will exclaim that his chin will keep him in the fight, then Roy will say something like "yeah, but you can't take too many of those Jim". I'ts not some great insight, it's just a blunt statement.
