The Buffalo Bills made history on Wednesday when they hired Kathryn Smith as the team’s Special Teams Quality Control coach. Smith is the first-ever full-time female assistant coach hired by an NFL team in the history of the league. Kathryn Smith worked during the 2015 season with the Bills as an administrative assistant to Ryan, and has a history with head coach Rex Ryan as she worked the same position with the New York Jets alongside Ryan in 2014.

The Arizona Cardinals made history last season by hiring Jenn Welter as a training camp assistant coach last summer, but she was not brought on as a full-time coach for the 2015 season.

Rex Ryan applauded his newest coach saying, “Kathryn Smith has done an outstanding job in the seven years that she has worked with our staff. She certainly deserves this promotion based on her knowledge and strong commitment, just to name a couple of her outstanding qualities, and I just know she’s going to do a great job serving in the role of Quality Control-Special Teams.”

“Kathryn has been working in a football administrative role and assisted the assistant coaches for years. She has proven that she’s ready for the next step, so I’m excited and proud for her with this opportunity. She will work with Danny Crossman and Eric Smith involving a number of responsibilities.”

Smith will replace former Special Teams Quality Control coach Michael Hamlin, who was let go by the Bills after just one year with the organization.
