Jen Welter Played Big To Become First Female NFL Coach

Despite her 5-foot-2, 130-pound frame, Jen Welter always excelled in athletics, from tennis to rugby to women’s football.  Welter credits her determination for helping her crack one of American’s most stubborn glass ceilings. In 2015, she became the first female coach in the National Football League, working with the Arizona Cardinals’ linebackers in the preseason. But as Welter writes in her new memoir "Play Big," it took years of adversity in life and sports before Welter found herself on the sidelines. Now, she hopes her story can inspire others.
