BECKY HAMMON made history last summer when San Antonio hired her as the first female full-time assistant coach in the history of major men's American sports. Last week she continued her pioneering ascent, leading the Spurs' Las Vegas Summer League squad to the 2015 title. It's not the first time that Hammon, 38, has overcome the odds. Despite going undrafted, she scrapped to build a 16-season WNBA career, for New York and San Antonio, earning six All-Star nods along the way, before playing internationally. Spurs head coach Gregg Popovich said in a recent radio interview that Hammon's hiring was no gimmick. "She's a coach, and she's good at it," he said. "I think it's a step in the right direction."
