The NFL keeps no such records, but it's safe to assume Vikings coach Mike Zimmer just became the first 63-year-old defensive guru to hire a 69-year-old defensive guru to be his (super?) senior defensive consultant.
"It did surprise me when he called," said the 69-year-old, Dom Capers.
Zimmer is heading into his 27th NFL season. And Capers has him beat by eight years.
"I think it was very smart of Mike to do something like this," said longtime Zimmer confidant Andre Patterson, now Vikings co-defensive coordinator along with Adam Zimmer. "Dom has seen a lot. To have a voice in that room to give us ideas, I think that's outstanding."
Zimmer was a defensive coordinator for 14 years, winning one Super Bowl with the Cowboys, and has been a head coach going on seven years. Capers was a defensive coordinator for 15 years, winning one Super Bowl with the Packers, and was a head coach for eight years.
"I just want another idea guy, really," Zimmer said. "Somebody to come in and maybe have a little better way of doing things than we've done in the past. … And then we all sit in a room and decide how we want to do things."
Zimmer carved out his NFL reputation with a 4-3 scheme featuring the Double A-gap pressure packages that have been copied leaguewide. Capers comes from a 3-4 scheme and was on the ground floor of the zone blitz craze that spread from Pittsburgh to all corners of the league.
"We had a lot of success with it, and within a few years a lot of people were zone blitzing," Capers said. "And the more familiar people become with [a scheme], sometimes it loses its effectiveness. And you have to look for the next edge."
