George Foreman wins the heavyweight title 20 years after losing it to Muhammad Ali.
Roy Jones Jr. wins the heavyweight title.
Manny Pacquiao's 7 divisional titles and 4 lineal titles.
Orlando Canizales's record 16 consecutive title defenses at bantamweight.
Joe Calzaghe retires undefeated.
Evander Holyfield regains the heavyweight crown a record 4 times.
Dodie Boy Penalosa, who has polio, wins the jr. flyweight and flyweight titles.

Just wondering what boxingscene thinks.
