While the media storyline for the Super Bowl is Aaron Rogers versus Ben Roethlisberger, or even Packers head coach Mike McCarthy versus Steelers head coach Mike Tomlin, the cognoscenti understand that the most interesting pairing involves the defensive coordinators, Steelers’ defensive guru, Dick LeBeau and his former protégé (and boss) Dom Capers. Capers, as defensive coordinator for the Steelers, coached with LeBeau back in the early 1990s, where Capers and LeBeau conspired to implement their madcap 3-4 zone blitz schemes that would help LeBeau land in the NFL Hall of Fame. (LeBeau, too, is not without his Green Bay connections, as he was an assistant for the Pack in the late ’70s under Bart Starr.) LeBeau took over as defensive coordinator in 1995 once Capers left to become head coach of the Carolina Panthers.
As is true today, change on defense was spurred on by change on offense. (Credit for much of this discussion must go to Tim Layden and his book, Sports Illustrated Blood, Sweat & Chalk.) By 1983, Bill Walsh already had his first Super Bowl and even won it against Cincinnati, where LeBeau was an assistant under Forrest Gregg and then Sam Wyche. LeBeau knew his defenses needed to evolve: Walsh’s precision offense could methodically slice apart zones, yet was dangerous enough to hit the big ones against a man-to-man blitz. Before the 1980s, the general but imperfect rule was that a four man rush meant zone, while a blitz meant man-to-man. According to Tim Layden:
“The one thing you knew,” says Steve Spurrier, who played quarterback in the NFL from 1967 through ’76, “was that if you saw a blitz, you were getting man-to-man defense behind it. That didn’t mean it was easy to deal with the blitz, but at least you knew what coverage you were going to get.”
So LeBeau began experimenting with schemes that showed blitz looks — and did in fact rush defenders from unexpected places — but nevertheless dropped a minimum of six defenders into zone coverage. To LeBeau, this was the perfect remedy: depending on the coverage you put behind the blitz, you actually were playing a very conservative defense, but the offense thought you were being aggressive, and, depending how intelligently you deployed your five rushers, you were being aggressive, albeit in a very controlled sense. Controlled chaos, indeed.
But these were still the dabblings of a scribbler. The next evolution came not from the wellspring of an NFL mind, but by a visit to Baton Rouge and Louisiana State University, where former Don Shula assistant and walking repository of football knowledge Bill Arnsparger coached. Arnsparger, who literally wrote the book on defense with his tome, Arnsparger’s Coaching Defensive Football, had experimented with zone blitz schemes for much of the prior fifteen years, including during the Miami Dolphins’ undefeated season. According to Layden and LeBeau, Arnsparger kept using the term “safe pressure” to describe the zone blitz, words that stuck with LeBeau: the zone blitz isn’t a kamikaze defense, it’s sound football, with an element of disruption. LeBeau would go on to develop these ideas for the next couple of decades, aided by an assistant in Pittsburgh named Dom Capers, and later to be (in my view at least) the biggest reason that Pittsburgh could win its third Super Bowl in six years.
(As an aside, an NFL coach once told me that anyone who understood every word in Arnsparger’s book would undoubtedly know more defense than every coach in the NFL. I immediately thought of LeBeau when he said this, but the point remains; indeed, Arnsparger’s name is aptly in the title of his tome, much in the way that Gibbon’s History of the Decline and Fall of the Roman Empire is the settled name for his masterpiece.)
With this background, it’s worth spending a bit more time on what the zone blitz is and how LeBeau and Capers use it. (more…)
