Blackshirts taking on identity of defensive coordinator Bob Diaco, as players, staff work to match his energy

Nebraska defensive coordinator Bob Diaco has kept the defense’s energy high during the start of fall camp. “The guys are on fire for what they’re doing, it’s very important to them, and it’s exciting,” Diaco said.

LINCOLN — Nebraska defensive coordinator Bob Diaco’s office overlooks the Huskers’ expansive weight room so, in theory, Diaco could step to the window to catch a glimpse of the workouts below. Diaco said in a summer interview that he didn’t care to do so — there was enough of his own work to keep him busy.

But Diaco’s teaching methods had already burrowed their way into the minds of Husker players to the point where, when the team did summer conditioning drills that coaches couldn’t attend, defenders acted like Diaco was there anyway.

“We wouldn’t slack,” defensive end Freedom Akinmoladun said. “We always stood up when we were tired. There was no failure in body language. We always pushed our best. Because we know how this defense is going to be run.”

The intense energy and enthusiasm that marked spring camp appear to have carried over to training camp. Whether Nebraska sustains it for a full month — the Huskers don’t kick off against Arkansas State for 32 days — is another question, but Diaco, ditching the gray sweatsuit for a black ensemble, sees total buy-in three days into camp.

NU’s defense, a perpetual Achilles’ heel since the program joined the Big Ten, needs all the buy-in it can get.

“The guys are on fire for what they’re doing, it’s very important to them, and it’s exciting,” Diaco said.

Diaco’s voice was hoarse. Trent Bray had a raspy voice, too. Defensive line coach John Parrella lost his entirely on day two.

“He thought it would come back today, and it was still gone,” defensive end Carlos Davis said of Parrella.

The defense as a whole rarely slows for a minute. Players jog to spots. Coaches are demonstrative. On Sunday, when NU’s defense started with its up-down warm-up drill, Parrella ran it.

Diaco wants his players thinking call-to-call, drill-to-drill, practice-to-practice. He wants them to shut out the big picture and focus on communication. He talks of players understanding his “language” and behavior being “habitized” to the point where it becomes second nature.

“If every single person on the unit, including the coaches, improves 0.001 percent each day, how can anybody be upset with that?” Diaco said. “Hopefully I did a better job today and the fourth-string boundary corner did a better job today and the starting mike linebacker did a better job today.”

He’s brought in a consultant, former head coach and defensive coordinator Gary Darnell, to help examine the big picture and serve as a sounding board.

Darnell, who’s collecting a $110,000 fee to help the Huskers’ defense, was once Diaco’s boss during his last year as head coach at Western Michigan in 2004. Darnell and Diaco remained close, even after Darnell formally retired after his final two seasons as Texas A&M’s defensive coordinator in the mid-2000s.

Diaco said he hired Darnell for his experience and his familiarity with several kind of defenses; Darnell mentored TCU coach Gary Patterson and others.

“He can cycle back through his Rolodex of information to the middle 1970s and think about something that might have hurt or helped,” Diaco said. “It’s like having an unabridged dictionary there.”

Darnell is the seasoning on the Huskers’ defensive staff, which is otherwise one of the youngest in recent Husker history. The oldest full-time assistant is Parrella at 47. All five coaches — Parrella, Diaco, Bray, safeties coach Scott Booker and cornerbacks coach Donte Williams — played college football in the last 25 years. All are in something close to playing shape, too.

Perhaps that’s why, when asked about Nebraska’s summer conditioning regimen — which players have said was much harder than previous years — Diaco shrugged it off.

“That’s like a prerequisite to being at this level,” Diaco said. “Every team trains hard.”
