Marcellus Baz's story, depicted in Man on a Mission: Breaking the Vicious Cycle of Crime, is a perfect illustration of how coaches working with young people likely to be at risk of getting involved in crime must develop flexibility, empathy, patience and, crucially, understanding of the world the people who attend their sessions live in.
"I'm big on punctuality," says Marcellus, the award-winning founder of the Nottingham School of Boxing, "but when one of the lads turned up 15 minutes late for training I didn't demand to know why."
Instead, Marcellus gave him the opportunity to share. The results illustrate just how crucial it is to develop a keen awareness and understanding of the people you coach.
