Muhammad Ali's grandson is continuing the Ali family boxing tradition. 24 year old Nico Ali Walsh tells us about his legendary grandfather and how Muhammad encouraged him to pursue his career as a boxing professional. He discusses the legacy of the Ali family, the expectations placed upon him, and how his Muslim faith influences his boxing career. His aunt, Laila Ali, who's now retired from the ring, offered Nico advice as insight. Nico also tells us about the physical dangers of boxing, including a severe injury he sustained and his determination to become a world champion. Every time Nico begins preparations for a fight, he says, he says he feels the presence of his iconic grandfather. He has seen every one of his grandfather's fights - he used to watch them with Muhammad. But, Nico says, he doesn't try to emulate him in the ring. He does, however, seek to emulate his grandfather's activism and commitment to social justice. Nico's ambition is to be world champion. 'It's a spiritual journey for me', he says.
