It's getting common these days that press conferences end up in brawls. It's sad. IMO boxing needs less people like Angel Garcia, and bring back guys like Floyd Patterson.
Great acts of true sportsmanship, off the top of my head:
- Barrera immediately kneeling and comforting Paulie Ayala who was still on his knees after a brutal body shot.
- Pacquiao refusing to KO Margarito in the late rounds, asking ref to stop the fight.
- Duran visiting his rival De Jesus who was dying of AIDS. Hugged and kissed at a time when little was known and so much feared about said disease.
Anything else? I'm sure Arguello had many moments but I don't know much about him.
