Jeff Hafley is the Defensive coordinator for the Green Bay Packers of the NFL. He was formerly the NCAA Men's Football coach at Boston College. Hafley was a four-year letterman (1997–2000) as a wide receiver on the Siena Saints football team and graduated in 2001 from Siena College with a bachelor's degree in history.
Prior to being hired by Boston College, Hafley was the co-defensive coordinator at Ohio State University. Hafley led a dramatic turnaround in leading the defense for Ohio State as the Buckeyes won the 2019 Big Ten championship and qualified for the College Football Playoff.
A standout defensive backs coach throughout his career in the NFL and collegiate ranks, Hafley's work as the defensive backs coach at Ohio State has led to impressive results. The Buckeyes totaled 15 interceptions in 2019, tied for ninth nationally while allowing just 25 pass plays of 20+ yards.
Before arriving at Ohio State, Hafley spent the previous seven seasons in the NFL and most recently three seasons with the San Francisco 49ers as defensive backs coach. Prior to his time with San Francisco, Hafley was the secondary coach for two seasons in Cleveland, the secondary/safeties coach with Tampa Bay in 2013, and a defensive backs assistant with the Buccaneers in 2012.
