Steve Belichick is related to Bill Belichick in two very different ways, and the confusion around the name has only grown as North Carolina’s 2026 football season unfolds. One Steve Belichick was Bill’s late father, a legendary Navy scout. The other is Bill’s son, currently the Tar Heels’ defensive coordinator and recently placed on medical leave.
Understanding this family tree matters right now because Steve Belichick, the son, has been a major storyline heading into North Carolina’s 2026 season. His absence from the sideline has fans searching for answers about who he is and how he connects to head coach Bill Belichick.
Two Steve Belichicks, One Famous Coaching Family
The Belichick coaching dynasty actually includes three generations sharing overlapping names. Bill Belichick’s father was named Steve Belichick. Bill’s oldest son also goes by Steve, though his formal first name is Stephen.
This overlap is not a coincidence. The younger Steve was named partly in honor of his grandfather, continuing a football lineage that now spans nearly a century.
Steve Belichick Sr.: Bill Belichick’s Father
Steve Belichick Sr. was born on January 7, 1919, in Monessen, Pennsylvania, the youngest of five children of Croatian immigrants John and Mary Bilicic. He grew up in Struthers, Ohio, during the Great Depression.
He played fullback at Western Reserve University from 1938 to 1940 and briefly appeared with the Detroit Lions in 1941. World War II interrupted his football career, and he served in the U.S. Navy, seeing action in Europe and in Okinawa in the Pacific theater.
After the war, Steve Sr. built a long coaching career. He served as head coach at Hiram College from 1946 to 1949, then as an assistant at Vanderbilt from 1949 to 1952, and at the University of North Carolina from 1953 to 1955.
His most defining chapter began in 1956, when he joined the U.S. Naval Academy as an assistant coach and scout. He remained at Navy for 34 years, retiring in 1989. During that span he became one of the sport’s most respected scouts, known for exhaustive film study and detailed opponent reports.
Steve Sr. wrote “Football Scouting Methods” in 1962, a book still referenced by coaches for its breakdown of scouting fundamentals. Bill Belichick has repeatedly credited that scouting philosophy as the foundation of his own coaching career.
Bill was born in Nashville in 1952 while his father coached at Vanderbilt, and the family later settled in Annapolis, Maryland, once Steve Sr. joined Navy’s staff. Bill grew up around the program, breaking down game film with his father from a young age.
Steve Belichick Sr. died of heart failure on November 19, 2005, at age 86, in Annapolis. He was survived by his wife, Jeannette, and his son, Bill.
Steve (Stephen) Belichick: Bill Belichick’s Son
The second Steve Belichick is Bill’s oldest child, formally named Stephen Belichick. He is currently the defensive coordinator at the University of North Carolina, working under his father for the second consecutive season.
Steve began his coaching career in 2012 as a defensive assistant with the New England Patriots, where his father was head coach. Over more than a decade in New England, he moved through several roles.
His Patriots coaching timeline includes:
- 2012–2015: Defensive assistant
- 2016–2018: Safeties coach
- 2019: Defensive backs coach
- 2020–2023: Outside linebackers coach, while also serving as the team’s defensive play caller during his final four seasons there
Before coaching, Steve played four seasons of lacrosse at Rutgers University and also joined the football team as a long snapper.
In December 2024, Steve took his first defensive coordinator job at the University of Washington. He helped the Huskies improve significantly on defense that season, and their pass defense ranked second in the Big Ten.
That same month, Bill Belichick was hired as North Carolina’s head coach, ending his 50-year run at the professional level. He brought his son along, naming Steve the Tar Heels’ defensive coordinator on December 22, 2024, reuniting the father-son pair.
North Carolina’s defense showed real progress in Steve’s first season in 2025. The unit ranked 30th nationally in yards per play allowed and finished 11th nationally in limiting explosive plays. However, the team still finished 4-8 overall.
Bill Belichick’s Coaching Sons
Steve is not the only Belichick son on his father’s UNC staff. Brian Belichick, Bill’s younger son, also coaches for the Tar Heels as the safeties coach. That arrangement has made North Carolina the first program where three Belichick family members coach together at once.
This three-generation coaching thread, from Steve Sr. at Navy to Bill in the NFL to Steve and Brian at North Carolina, is central to how the family is covered in football media today.
Steve Belichick’s Medical Leave Ahead of the 2026 Season
The Steve Belichick and Bill Belichick connection has drawn fresh attention because of recent news out of Chapel Hill. On August 6, 2026, Bill Belichick announced that his son Steve was going on medical leave from the program.
Bill offered no details about the nature of the situation. “It’s a medical situation, so I really can’t make any further comment on that,” he told reporters, adding only that he hoped to have his son back “as soon as possible.”
Steve did not travel with the team for North Carolina’s 2026 season opener against TCU, played on August 29 at Aviva Stadium in Dublin, Ireland. His absence came without an announced timeline for return.
Rather than naming a single interim defensive coordinator, Bill Belichick said the defensive staff would handle coaching duties as a group. Defensive line coach Bob Diaco has taken on a larger role in game planning, and Bill himself has retained defensive play-calling responsibilities in his son’s absence, a role he knows well from his Patriots years.
As of early September 2026, Steve Belichick remains on indefinite medical leave, and North Carolina has not provided an updated timetable for when he might rejoin the coaching staff.
Why the Family Connection Keeps Coming Up
Steve Belichick’s name recognition comes from two distinct legacies. The grandfather built a scouting reputation over three decades at Navy that shaped how Bill approaches game preparation. The son has followed his father directly into coaching, working alongside him in New England and now at North Carolina.
Both men share more than a name with Bill Belichick. Steve Sr. is the reason Bill became a coach in the first place, and Steve the younger has spent his entire adult coaching career working directly under his father’s staffs, first with the Patriots and now with the Tar Heels.
North Carolina fans and college football observers will be watching closely to see when Steve Belichick returns to the sideline, and how his absence affects a defense trying to rebound from a difficult 2025 campaign.
