While Marc Trestman continues to seek the right fit for a wide receivers coach, the Bears coaching staff is assembling a playbook from scratch.

Offensive coordinator/line coach Aaron Kromer talked Thursday about the process at the simplest level — making sure everyone is using the same verbiage to describe formations and motions. From there, the playbook is being created.

When it's ready to be unveiled, the Bears offense will be a hybrid attack because of the numerous influences. Running backs coach Skip Peete said Trestman even might bring some successful concepts from Canada that should translate.

"Marc and I have a history together back with the Oakland Raiders and we had a lot of success there, and obviously the New Orleans offense has been very successful lately," said Kromer, who was the Saints' line coach the last four seasons and designed their running game.

"It will be a combination of a lot of things, and you don't want an offense to get stagnant, so you are constantly researching and finding new things that you can add to make it better and more versatile."

Kromer, who declined to talk specifically about any players he is inheriting, comes with a solid track record. The Saints were known for a high-powered passing attack, but they ran the ball with consistent success. Twice in the last four seasons, they ranked in the top five in the NFL in yards per carry, and that was without the benefit of a quarterback who can scramble and boost the average.

The only season they struggled, injuries forced the Saints to use eight running backs in 2010. Situationally, they have had one of the better rushing offenses in the league.
