When Jontay Porter was ten, his father woke him up most mornings before dawn. He and his siblings piled into the family's Sprinter van and drove to an empty field house off the highway. Then, while their friends slept, they ran basketball drills with their father. "All I remember is it still being pitch-black outside, and the two dreaded double doors on the side of the building that would always be left open for us," Jontay told me recently. In the bleary moments just before one of his siblings tugged the field-house doors open, Jontay always secretly wished that they'd be locked. And, one morning, they were. Jontay smiled as he climbed back into the van and drifted off to sleep. But his brother Michael, Jr., who was seventeen months older, was furious. "Michael was the opposite," Jontay said. Jontay grew up in Columbia, Missouri, the fourth of eight children. His father, Michael, Sr., worked in Christian ministry, and his mother, Lisa, homeschooled the children. Both had played college basketball--Lisa, as a high-school senior, had averaged a nearly impossible fifty-eight points per game--and they saw the sport as their children's ticket to college. All eight of the kids eventually got basketball scholarships. By the time Jontay was sixteen, he was six feet ten. In most families, as a five-star high-school recruit, Jontay would have been the main attraction. In 2010, their father got a job on the coaching staff for the women's team at the University of Missouri. The men's coach spotted Michael shooting alone in the arena one night and offered him a full scholarship; he was still in seventh grade. When he accepted it, as a high-school senior, he was the top recruit in the country. His highlight reels had racked up millions of views on YouTube. N.B.A. scouts believed that he could be the next Kevin Durant. "He's a game-changer," a league executive told the New York . Big state schools turn their best athletes into local celebrities, but the hype that followed Michael to Missouri's campus on his recruiting visits was closer to Beatlemania. Fans asked for autographs and took selfies. Jontay, who came along, was seduced by the hysteria. "Frat houses are putting up posters, and he's literally treated like a king," he recalled. "I wanted to be a part of that circus." He skipped his senior year of high school to join the team, too. The brothers were best friends. Still, it was sometimes hard to be one of the top players in the country but just the second best in his family. "He got all the attention," Jontay said.
