He knows the moment he fell in love with the sport.
He was tiny, just like the little ones — age 5, age 6 — who constantly skip around the sweat-stained blue floor of the Minneapolis garage-turned-gym known as the Circle of Discipline.
Back then, Jamal James wasn't yet a 19-0 professional welterweight. He didn't have the nickname "Shango," for the African god of thunder. He wasn't managed by one of boxing's premier managers, Al Haymon — the same guy who works with Floyd "Money" Mayweather Jr.
He was just 4 years old when he heard the rhythm of the speed bag for the first time. A boxer's fists ripped through the air and jostled the little bag like a tuning fork.
James stared, then pulled a chair to the bag. He balanced on it and started hitting.
Hours went by. He wanted to make the rhythm himself.
Moments like that happen every day in the gym on E. Lake Street, a place that draws people in with boxing, then changes their lives.
James, now 27, is awaiting word on a nationally televised fight that would give him a chance at a spot among boxing's elite.
