Copy shortlink: Sarah Holmgren remembers asking her then 8-year-old son Chet what he wanted to be when he grew up. "He said 'A pro basketball player,' " she recalled. "There were long odds against that, so my husband, David, and I asked him about a back-up plan. "David and I disagree on our memories of this. David remembers him saying he was going to be a pro football player. I remember him saying he was going to be an astronaut, which has worse odds than going pro. When we said that those odds were worse, he remarked with 'I know, so leave me alone.' He's always been laser-focused on his goal."
