"Its an honor to join a staff of not only talented coaches but men of quality character," said Shaw on Tuesday. "My family and I are excited for this new chapter and are thankful to be part of something special at Furman University!"
Shaw left South Carolina with a 27-5 record as a starter and a 17-0 record at Williams-Brice Stadium. He declared for the NFL Draft in 2014 but was signed to the Cleveland Browns for two seasons as an undrafted free agent.
He eventually was cut from the team and picked up by the Chicago Bears for two seasons before being cut there as well.
Shaw still holds records at USC for completion percentage in a game, consecutive passes completed in a game, single-season completion percentage, consecutive passes in a season without an interception, and touchdowns responsible for in a season and in a career.
