Only 705,000 viewers tuned in to watch ESPN's D. Wade: Life Unexpected, a candid look at Dwyane Wade's life on and off the court.

The documentary drew Less than 1 million viewers despite the heavy press coverage of Wade's gender confused child, Zion Wade, a 12-year-old boy who calls himself Zaya and prefers feminine pronouns.

In addition to Zaya, the former Miami Heat star and his wife, actress Gabrielle Union, 47, share 18-month-old daughter Kaavia James. He is also father to 18-year-old son Zaire and 6-year-old son Xavier, whose mother is family friend, Aja Metoyer.

Esquire magazine breathlessly called the documentary "a groundbreaking portrait of modern fatherhood" and "a breakthrough as a sports documentary" that "calls attention to the way we've viewed and discussed fatherhood in past years."

In the documentary, Wade, 38, talked about how, when he was "on a break" from Union, he fathered Xavier. And about his public divorce from his first wife, Siohvaughn Funches, with whom he reached a $5 million settlement that included an NDA agreement.

Esquire referred to Wade's announcement about Zaya "the highest point" of the documentary.

"I looked at her and said, 'You are a leader. You are a leader and this is our opportunity to allow you to be a voice," Wade told openly lesbian TV host Ellen Degeneres.

"Right now it's through us because she's 12 years old, but eventually it'll be through her," Wade said.
