The billionaire who is bringing NFL football back to Houston likes horses, charity, and taking chances. Bob McNair looks serenely happy. No, that doesn’t quite describe him. He looks transcendently happy, standing in the hot, late-summer sun on a stage that has been constructed in the middle of a street in downtown Houston, surrounded by hundreds of adoring fans who are waiting for the formal unveiling of their brand-new hometown football team, the Houston Texans. At this moment, in September 2000, McNair, who is the majority owner, chairman, and CEO of this new NFL franchise, is very likely the most beloved man in Houston. He is wearing a blue “ NFL 2002” polo shirt, signifying the year the Texans will play their first game, and sipping from a bottle of water. He is approached by fans who tell him how wonderful he is. “Thank you, Bob,” they say, with a sort of breathless gratitude. Others shout, with deep sincerity, “Bob, you’re the best!” At this moment, it is good to be Bob McNair.
