"If it wasn't for my coaches, uncle and auntie, I wouldnt have been able to do this," said Demontaze "Juicy" Duncan. Demontaze, 12, and his brother, Demetrius "Man-Man" Duncan, 14, are preparing to compete at the Ringside World Championships in Independence, Missouri. In 2007, when they arrived home from school, the brothers found their mother beaten to death inside the house. That situation, according to their coach, Nicholas Bareis, fuels their energy in the ring.
