Lawyer Leigh Steinberg had no big dream to become a sports agent. He was a huge sports fan, but the job was not something he was aspiring to – more something that he stumbled across. Today, he's built up a career representing more than 300 professional athletes across a range of disciplines: from big money-making sports like football and basketball, to Olympic gymnastics; building sporting careers worth billions of dollars. His influence in sport is so influential that he's often credited as the real-life inspiration for the sports agent in the film Jerry Maguire, starring Tom Cruise.We speak to Leigh Steinberg about how he started his career as an agent, how he builds a brand around a sports star, and how he's succeeded in such a competitive environment - overcoming some personal struggles along the way. And - how he responds when members of the public approach him with the famous phrase, "Show me the money".(Picture: Leigh Steinberg.
