Owings Mills, Md. ? Brian Billick never came close to duplicating the success he enjoyed early in his career as head coach of the Baltimore Ravens, and it finally cost him his job.

Billick was fired Monday, less than 24 hours after his team concluded a season of high expectations with a disappointing 5-11 record. His entire staff, including defensive coordinator Rex Ryan, also was dismissed.

“I believed that it was time for a change, I believed that we have the nucleus of a team that can get back to the Super Bowl, and we felt that in the next five years we had a better chance with a new coach than leaving Brian in that position,” said owner Steve Bisciotti, who made the decision after consulting with team president Dick Cass and general manager Ozzie Newsome.

Billick won the 2001 Super Bowl in his second season with the Ravens, but since Bisciotti took over full ownership in 2004, Baltimore was 33-33. That included two losing seasons and only one playoff appearance, a one-and-out performance in 2006.

“It’s a gut feeling. I have one job here, and that’s to have a leader that I think gives us the best chance,” Bisciotti said. “We have been losing more than winning lately.”

Billick led the Ravens to a franchise-best 13-3 record in 2006. But Baltimore lost a team-record nine consecutive games this season before ending the skid Sunday with a 27-21 victory over Pittsburgh.

Bisciotti said he made the decision to fire Billick hours before kickoff and carried out the move Monday morning in a meeting at the team’s practice facility.

“He had to make a hard decision, and he did what he believes is best for the Ravens,” Billick said. “We are friends and will remain friends.”

Billick had three years left on a contract that pays $5 million per year.
