Among other things, he said, he never refused to fly, but rather, he insisted that the teams let him travel by bus when possible (he made several trips by plane while with the 76ers). Nor, he said, does he typically feel anxious while he is playing, only beforehand and at odd moments he cannot always predict.

He is not cured, he said, but rather “very aware of my triggers.”

The biggest of these is his obsessive-compulsive tendency, which strikes when he feels things are spinning out of control.

“Being disorganized makes me really anxious,” he said.

His house was so clean, so devoid of mess or clutter, that it was as if no one lived there at all — let alone a 22-year-old with a wife and two small children, aged 2 ½ and 6 months. The three of them were upstairs somewhere, White said, and certainly no noise gave them away; the only sign of children was a pair of tiny sneakers by the door and a plastic basketball hoop that came up to about White’s waist in the living room.

White’s own possessions are in strict order. His clothes are organized by “brands and color schemes, the way they would in the store,” he said.

His extensive DVD selection is alphabetized, according to a system he devised to deal with the vexing question of movies beginning with “The.” Under his scheme, “The Goonies” goes with the T’s, because “The” is integral to the title; “The Great Debaters,” about a college debate team, goes with the G’s, because “The” is ancillary (it makes sense to him).

Unlike many professional sports players consumed to the point of tunnel vision about their sports, White has a constellation of nonsports interests. There is the clothing line he and his wife, a former model, are planning to set up. There is his Twitter account, in which he provides words of inspiration and random musings to more than 445,000 followers and responds to abuse with the hashtag, #BeWell. There is his charitable foundation, Anxious Minds, and the new Royce White Mental Health Institute that just broke ground in Houston. There is his record label, which has signed one band so far. (He writes music as a hobby, he said.)
