Kathryn Smith became the NFL's first female full-time assistant coach Wednesday, when the Buffalo Bills hired her as a special teams quality-control coach, a move she acknowledged as "groundbreaking" on the team's website (via Mike Rodak of ESPN.com).
It undoubtedly was groundbreaking, but Jen Welter helped paved the way for Smith. Welter became the first woman to coach in the NFL when she was an intern with the Arizona Cardinals during their 2015 training camp. According to Josh Weinfuss of ESPN.com, Welter was happy to see the NFL moving forward in terms of hiring women.
