He went on to play at UCLA from 1984 to 1987, where he was converted to linebacker, the position he would play for the remainder of his football career.
Norton was a member of the 1985 conference championship team, and helped the Bruins to four consecutive bowl game wins. He led the team with 106 tackles in 1986 and 125 in 1987. He ranks sixth in school history with 339 career tackles.
He was named the team's defensive MVP in 1987, earned first-team All-American honors, and was a finalist for the Butkus Award.[1]
Norton was inducted in the UCLA Hall of Fame in 1998.
In 1989, Norton and Jesse Solomon shared the weakside linebacker position. He played the first and third quarters, Solomon the second and fourth.
In 1990, he became a full-time starter when Solomon held out and was eventually traded to the Tampa Bay Buccaneers. A knee injury sidelined him for the last two games of the season.
In 1991, he bounced back from knee surgery and was used at strongside linebacker and middle linebacker during that season, eventually settling in at the middle linebacker spot.
In 1992, he blossomed as a player and became the leader of the defense, leading the team in tackles with 120 and helping the Cowboys win their first Super Bowl in the 1990s. That year the Cowboys had the number one defense in the league, but no player was voted to the Pro Bowl.
He also started doing his trademarked punching of the goal posts or the air, after making good plays. A tribute to his father, the one time boxing heavyweight champion of the world, Ken Norton.
In 1993, he had to play through a torn biceps injury,[4] but still managed to lead the team in tackles with 159, helping the Cowboys win their second straight Super Bowl. He was also selected to his first Pro Bowl. Norton played in Dallas between 1988 and 1993, assisting the Cowboys to victory in Super Bowl XXVII and Super Bowl XXVIII. Norton scored his first career touchdown on a fumble recovery in the fourth quarter of Super Bowl XXVII, helping to seal a Cowboys victory.
In 1994 when a salary cap was instituted in the NFL, the Cowboys organization felt they could find linebackers through the draft, without the need of paying a premium and adversely impacting the salary cap, so they allowed talented and productive players like Ken Norton Jr., Darrin Smith, Dixon Edwards, and Robert Jones to leave via free agency, instead of signing them into long-term contracts.
San Francisco 49ers (1994–2000)
During the first year of free agency, he joined the San Francisco 49ers from 1994 to 2000. He became the first player to win three consecutive Super Bowls when the 49ers won Super Bowl XXIX, a feat that remains unmatched as of 2024. Norton was selected to his second Pro Bowl in 1995. Norton was also named to the NFL All-Pro Team following the 1995 season. Norton is also notable for his part in ending the career of Napoleon McCallum. In the first game of the 1994 season, Norton, along with Bryant Young, tackled McCallum during a rushing play. While he was being pulled to the ground, McCallum's knee collapsed backwards into an unnatural position, almost at a 90-degree angle. After the play, Norton remained under McCallum while medical staff attended to McCallum.
Norton finished his 13 NFL seasons with 12 sacks and 5 interceptions, which he returned for 127 yards and 2 touchdowns (both in the same game against the St. Louis Rams in 1995). He also recovered 13 fumbles and returned them for 36 yards. Along with ex-teammate Deion Sanders, Norton won consecutive Super Bowls on different teams. Years later, LeGarrette Blount and Chris Long would become the third and fourth players to do so.
On January 7, 2009, Norton was promoted to USC Assistant Head Coach for Defense. A form of recognition of his continuing work with the USC linebacker corps, he has developed three consecutive Rose Bowl MVPs: Brian Cushing (2007), Rey Maualuga (2008) and Kaluka Maiava (2009).[5]
Attending the player evaluations of the by-invitation-only 2009 NFL Scouting Combine were all four of Norton's Trojan senior class linebacker protégés: Brian Cushing, Kaluka Maiava, Clay Matthews III, and Rey Maualuga.
Seattle Seahawks (2010–2014)
On January 11, 2010, it was announced that USC linebackers coach Norton would be joining head coach Pete Carroll in Seattle to fill the same role with the Seahawks, reuniting him with his protégé, Seahawks defensive standout Lofa Tatupu.[6]
Norton would also win his fourth Super Bowl, Super Bowl XLVIII on February 2, 2014, his first as a coach.[7]
On February 6, 2015, he was named the defensive coordinator for the Oakland Raiders. The Raiders also signed Seattle Seahawks outside linebacker Bruce Irvin reuniting him with his former coach.
He was fired by head coach Jack Del Rio on November 21, 2017, two days after the Raiders suffered a blowout 33 to 8 loss to the New England Patriots and the defense having not intercepted a pass in 11 weeks.
San Francisco 49ers and Seahawks (2018–2021)
On January 8, 2018, he was hired as the 49ers assistant head coach,[8] leaving the position just 1 week later when the Seahawks hired him as defensive coordinator.[9] Norton was fired after the conclusion of the 2021 NFL season lasting 4 seasons in his second stint with the Seahawks.[10]
UCLA Bruins (2022–2023)
In February 2022, Norton returned to UCLA as linebackers coach under head coach Chip Kelly.[11]
