His son, Wade Phillips, has also held assistant and head coaching jobs in the NFL and was the head coach of the Dallas Cowboys from February 2007 to November 2010. Wade was hired by the Houston Texans on January 5, 2011, as their new defensive coordinator almost exactly 30 years after his father was terminated by Oilers owner Bud Adams on December 28, 1980, after the Oilers failed to advance past the first round of the playoffs. Wade won a Super Bowl title at Super Bowl 50 with the Denver Broncos as defensive coordinator, and was the defensive coordinator of the Los Angeles Rams who advanced to Super Bowl LIII and later parted ways with the Rams following the 2019 season.
