The Falcons’ coaching staff films each pass Ryan throws in practice before and during the season to give the team an exact number of the wear and tear on his right arm. It’s an approach Atlanta started in 2008 when general manager Thomas Dimitroff and coach Mike Smith were hired and Ryan was drafted with the NFL’s third overall pick.
