The familial connection often extends to the sidelines. Former New England Patriots head coach Bill Belichick had his son Steve on his staff in Foxborough, and San Francisco 49ers head coach Kyle Shanahan is the son of legendary Denver Broncos head coach Mike Shanahan.

While the 49ers are eliminated and Belichick is now the head coach of the North Carolina Tar Heels, there is a legacy coach making his playoff debut as a defensive coordinator for the Los Angeles Rams this weekend: Chris Shula.

Here is everything you need to know about the Shula family.

Is Chris Shula related to Don Shula?

Chris Shula, first-year defensive coordinator for the Rams, is the grandson of Hall of Fame, Super Bowl-winning head coach Don Shula.

Chris played college football as a linebacker at Miami of Ohio from 2004-08 where he was teammates with current Rams head coach Sean McVay. After three different college coaching jobs, Chris broke into the NFL in 2015 as a defensive quality control coach for the San Diego Chargers.

He joined the Rams in 2017 as an assistant linebackers coach, connecting with his old college teammate. When the Rams won Super Bowl LVI, Chris had been promoted to linebackers coach. The following year, he became the pass game coordinator and defensive backs coach. Last season he was the pass rush coordinator and linebackers coach.

When former Rams defensive coordinator Raheem Morris accepted the Atlanta Falcons head coaching position last offseason, Shula was promoted. Despite losing future Hall of Famer Aaron Donald, Shula kept the Rams in the middle of the pack defensively, enough to help them secure an NFC West title and playoff berth.

His grandfather, Don Shula, coached the Baltimore Colts from 1963-69, winning the AP NFL Coach of the Year three times during his stint. In 1968, he led the Colts to a 13-1 record and a win in the NFL Championship Game. In 1970, Shula was hired to be the head coach of the Miami Dolphins, where he remained for the next 26 seasons.

While with the Dolphins, Shula only had two losing seasons. He led the Dolphins to 11 division titles, five AFC championships, and back-to-back Super Bowls in 1972 and 1973. His Super Bowl 7 victory completed the only undefeated season in NFL history when Miami finished the 1972 season with a perfect 17-0 record. That year, he won his fourth NFL AP Coach of the Year Award, the most in NFL history.

He also holds the all-time regular and postseason win-loss record of 347-173-6.
