Pittsburgh Steelers: Defensive coordinator Tim Lewis will be looking for a new job after coach Bill Cowher fired him Tuesday. Despite leading the Steelers to the No. 1 overall defensive ranking in 2001 and to No. 7 and No. 9 rankings over the next two seasons, Lewis couldn't keep his job. But Lewis revealed that his firing wasn't based on performance, but an undisclosed set of circumstances. "It really was not a football thing," he told the Pittsburgh Post-Gazette. Some players were taken aback by Lewis' sudden dismissal. "I'm surprised. I didn't see it coming," CB Dewayne Washington said. "The defense wasn't worse than last year. We wanted to improve on third downs and in the red zone and we definitely did that. At the end of the day, the players play and the coaches can only do so much." There was also another change on the staff, as Cowher decided not to renew the contract of wide receivers coach Kenny Jackson. But coordinator Mike Mularkey, whose offense went from No. 7 to No. 22 kept his job and Cowher's faith.
