The Giants yesterday hired Sean Ryan as their new offensive quality control coach.

Ryan comes to the Giants from Harvard, where he spent the 2006 season as recruiting coordinator, running backs coach and head coach of the junior varsity. He takes over for John DeFilippo, who was the quality control coach the previous two seasons.

DeFilippo and Ryan worked together at Columbia University in 2003 and 2004, with Ryan working as the running backs coach and special teams coordinator and DeFilippo the quarterbacks coach. Prior to Columbia, Ryan spent two seasons as a graduate assistant at Boston College, where he worked primarily with the wide receivers. He’s a native of Hudson Falls, N.Y.
