INDIANAPOLIS — When interim coach Tony Sparano made a plea to keep his job as coach of the Oakland Raiders, he preached continuity.

The early stages of the Jack Del Rio regime have demonstrated that the same old, same old isn’t what owner Mark Davis had in mind.

By the time Del Rio was finished constructing his coaching staff, only three holdovers remained: defensive backs coach Marcus Robertson, offensive quality control coach Nick Holt and defensive quality control coach Travis Smith.

The rest were sent packing far and wide to other NFL locales.

Del Rio said sweeping out the old in favor of the new wasn’t necessarily part of the plan and that it just turned out that way.

“I really didn’t look at it like that,” Del Rio said. “Several of the guys were cleared out before I got there. I didn’t speak directly with some of them. I went through a very deliberate process and spent a lot of time putting together the makeup of the current staff.

“I was not in a rush. I think the first time around as a head coach, I might have thought there was some kind of prize at the end of it if I got through in record time. I didn’t feel that pressure this time.”

What Del Rio ultimately sold Davis on was sweeping change in terms of the way the Raiders do things. The idea of continuity, considering the Raiders haven’t had a winning season since 2002 and are 11-37 over the past three years, wasn’t something Davis had in mind.

So the Raiders will run entirely new systems of offense, defense and special teams with offensive coordinator Bill Musgrave, defensive coordinator Ken Norton Jr. and special teams coordinator Brad Seely.

Musgrave will institute some quick-tempo no-huddle offense picked up in Philadelphia, where he was quarterbacks coach in 2014. Norton will attempt to light a fire under a defense that hasn’t been in the upper echelon of the NFL in a dozen years.

Change was also the theme in the way the Raiders will go about strength and conditioning. Three coaches arrive with no NFL experience but with expertise that Del Rio considers to be “cutting edge” in the field.

Strength and conditioning coach Joe Gomes has been director of performance for EXOS (formerly the Athletes Performance Institute) for the last few years, with Wesley Miller as one of his associates. Kevin Kijowski was also hired.

The training area is in the process of being upgraded and remodeled, and Del Rio talked of the “regeneration” of muscles over the course of a long season.

“They’re cutting edge in terms of innovation and what we need to do with our team to give them a chance to be their healthiest and at their peak on Sundays,” Del Rio said. “Players will be very excited about what we’re doing.”
