ALAMEDA — In his job as the Raiders’ defensive coordinator, Ken Norton Jr. borrows from his father’s sport.

Every Raiders defensive scheme is named for a heavyweight boxing champion.

“We have Tyson, we have Holyfield, we have Ali, we have Foreman, we have Frazier,” Norton said.

He’s even incorporated a “Fury,” named after Tyson Fury, currently a heavyweight champ from the United Kingdom.

Norton’s father fought Muhammad Ali three times. He fought George Foreman once. He never fought Joe Frazier, because they were friends.

Last season, Norton’s first as a coordinator, he set up the Raiders’ season as a 16-round boxing match.

“I would show them a championship round and use each game as a round,” Norton said. “We’d talk about what it took to get through that round — the grit, the smarts, the toughness, the defense, the aggression. All the things it takes to get through a championship round.”
