There are 3 different groups. Win = 3 points. Draw = 1 point Loss = 0 points. The fighters within each Group face off amongst themselves, fighting the other four in their own group. 2 leaders from each group, thus 6 go through to the next round in total. Therein the 2 leaders from Group A will form a new group with 1 leader from Group B - Let's call it group N1. 2 leaders from Group C will form a new group with the other leader from Group B - Let's call it group N2. If scores are tied within a group, those who are tied will fight eachother. The winner of Group N1 will go up against the winner of Group N2 in the final. The runner-up of Group N1 will go up against the runner-up of Group N2 to be the bronze medalist. Imagine they are all in good condition. Start by focussing just on Group A, otherwise it could get disorganised. Group A Hearns Mayweather Basilio Rodriguez Benitez Group B Whitaker Napoles Griffith Duran Gavilan Group C Leonard De La Hoya Curry Robinson Pacquiao If I had to bet on anything when it's all said and done, Thomas Hearns would be the safest bet for me.
