    Bill O'Boyle has completed three seasons on the staff at Southern Illinois. He was promoted to offensive coordinator for the 2014 season and assistant head coach for the 2015 season. He served as the offensive line coach in his first season, 2013.

    In O'Boyle's three seasons at SIU, the Salukis have improved scoring offense and passing offense in each season. In 2014, the Salukis set a program record for touchdown passes and scored the most points in a single season since 2009. After O'Boyle was promoted to assistant head coach in 2015, the program averaged nearly 500 yards total offense per game, second-best in program history. SIU set a program record with 298 passing yards per game in2015.

    In O'Boyle's three seasons overseeing the offensive line, SIU allowed the fewest sacks in the league despite dropping back to pass more than anyone else in the league. SIU led the conference in fewest sacks allowed in both 2013 and 2015 while ranking second in 2014.

    Prior to joining the Salukis, he was the offensive coordinator at Colorado Mesa University in 2012.

    From 2005-11, O'Boyle was the head coach at Chadron State, where he compiled a 54-22 overall record, including three-consecutive undefeated regular seasons and three Rocky Mountain Athletic Conference titles from 2006-08. His .750 winning percentage was the third-highest for active coaches in Division II entering the 2011 season.

    Under O'Boyle's guidance the Eagles won 28-straight RMAC games and earned three NCAA Division II playoff berths, advancing to the quarterfinals in 2006 and 2007 and to the second round in 2008.

    As head coach at Chadron State, Bill O'Boyle was named the Liberty Mutual Division II Coach of the Year in 2007.

    A three-time RMAC Coach of the Year, O'Boyle was named the Liberty Mutual Division II Coach of the Year in 2007. Twice, he was named American Football Coaches Association Region 5 Coach of the Year, and he was also the 2006 Sportexe Division II Coach of the Year and Football Gazette National Coach of the Year.

    He coached 13 All-Americans and nine Academic All-Americans during his tenure at Chadron State. Included on his list his former players are San Diego Chargers running back Danny Woodhead and Cleveland Browns offensive lineman Garret Gilkey.

    O'Boyle started as a graduate assistant and then assistant coach at Chadron State in the late 1980s. From 1990-1994 he spent four years at Western Illinois, his alma mater, as the offensive line coach and strength coach. He returned to Chadron State, and prior to his head coaching duties, he was the Eagles' offensive line coach and strength coach. In 1999, he became the Eagles' offensive coordinator.

    O'Boyle has strong ties to both SIU and the Missouri Valley Football Conference. His uncle, Tom O'Boyle, was the Salukis' defensive coordinator under Dick Towers from 1968-73. Two brothers, Mike O'Boyle and Dennis O'Boyle, lettered in football at SIU in the early 1970s. Two more brothers, Kevin O'Boyle and Tim O'Boyle, played football at Southern. Bill played and coached football for MVFC school Western Illinois. Bill has one daughter, Cassie.
