I saw Bam, and his brother Big, years ago in Texas. At that point in time Bam was ranked #2 in the world as an amateur, as a junior. He had all his amateur fights as an amateur as he turned pro at 16, I think. He was a very well schooled boxer, wicked body puncher. San Antonio, Texas, is a real hotbed for amateur boxing, and some really solid pros. Bam is going to do big things in the game.
Back then there was a young man, 11 or 12, called Panterita Martinez. He is now 18 or so, and he has been tearing it up on the amateur circuits.
