Besides James Toney and Duran, who were some other ones that were just so relaxed at all times in the ring..
Salvador Sanchez. Before his fight with Gomez he had a nice grin on his face lol, he didn't have a worry in the world. Alexis Arguello seemed pretty relaxed in there. Carlos Monzon deserves a mention, he came in there with a gameplan and wasn't going to be thrown off it, he was relaxed and his face never changed. Also has anyone noticed the connection that all 3 of these had terrific stamina for 15 rounds. As Manassa once said, Carlos Monzon could possibly be the best 15 round fighter ever.
I was amazed how relaxed Marco Antonio Barrera was in the ring as his career progressed. Even during viscious exchanges, Barrera was still cool and collected - keeping his punches crisp, loose, and precise.
