The Facts: HC Jon Gruden just told reporters at the Senior Bowl that Brian Callahan was leaving his staff to become the offensive coordinator in Cincinnati.

Diehards Line: Callahan was hired as the Raiders quarterbacks coach last offseason, after stints with the Lions and Broncos. Of course, the Bengals are hiring Zac Taylor as their head coach/offensive genius so he’ll likely call plays, and it could be a first step toward a family reunion. There have been reports that Taylor also wants to bring Brian’s father, longtime NFL assistant Bill Callahan in as well. Callahan is working for Washington at the moment.
