It's disorder and confusion when the Raiders have the ball and Greg Olson is the man responsible.

Only for a change the turmoil is happening on the other side of the line of scrimmage.

That's how former Raiders coach and ESPN "Monday Night Football" analyst Jon Gruden described what Olson is doing with the Oakland offense in a recent phone interview.

"What Greg has done is created a lot of chaos" Gruden said.

Gruden who hired Olson as his quarterbacks coach with the Tampa Bay Buccaneers in 2008 will call the Raiders' game Monday night against the Denver Broncos at Sports Authority Field.

Olson calls Gruden one of his biggest influences as an offensive coach citing his "presentation and preparation" as well as Gruden's belief of being a team that applies pressure rather than feeling pressure.

During his film study in preparation for the Broncos and Raiders Gruden can see Olson tailoring an offense for quarterback Terrelle Pryor that can put pressure on a defense.

"You're going to have to deal with (Darren) McFadden; on the other side you're going to have to deal with Pryor and the option the zone read and all the nuances that go along with that" Gruden said.

"I've seen Wildcat formations. I've see shifts to no-back sets. I've seen them bring in (Matt) McCants a big offensive tackle to play tight end. You're seeing a coordinator that's doing everything he can to adapt to a new quarterback."

It's a philosophy counter to the one held by previous offensive coordinator Greg Knapp who will be on the opposite sideline as quarterbacks coach of the Broncos.

Knapp unapologetically believed in zone runs and a West Coast system with a moving pocket with the players asked to adjust to his system. To deviate Knapp explained last season would be like a college professor teaching a subject other than the one he knows best.
