A sports agent is a legal representative for professional sports figures such as athletes and coaches. They procure and negotiate employment and endorsement contracts for the athlete or coach whom they represent. In addition to contract negotiations, sports agents may also help their clients with financial planning, legal issues, and marketing. They may work closely with financial advisors, lawyers, and marketing professionals on behalf of their clients.
