CLEVELAND - The Cleveland Browns announced Sunday that New York Jets assistant Romeo Crennel has accepted a job with the Browns to become the team's new defensive coordinator.Crennel decided to leave the Jets after three years as the team's defensive line coach, despite being offered a promotion to become the defensive coordinator under soon-to-be-named Jets head coach Al Groh."I am really pleased to have Romeo join us," Browns head coach Chris Palmer said in a press release on Sunday. "He is an outstanding coach. It strengthens your organization anytime you can acquire someone with 19 years of NFL experience."The long-time Bill Parcells assistant was rumored to be Palmer's first choice to be the Browns defensive coordinator when he was putting his staff together before the 1999 season, but the Jets denied a request for an interview.Crennel and Palmer served together as assistants on Parcells' coaching staff with the New England Patriots from 1994 to 1996.In 2000, Crennel will begin his 20th year as an NFL coach. His first NFL job came in 1981 as a member of Ray Perkins' staff with the New York Giants. With the Browns, Crennel will be reunited with Perkins, who currently serves as the Browns' tight ends coach.Bob Slowik, who served as the Browns defensive coordinator in 1999, has been told to either look for other employment or accept a demotion.When Dave Wannstedt was named the head coach of the Miami Dolphins last week, replacing the retired Jimmy Johnson, there was wide-spread speculation in the NFL that Slowik (an old friend and former assistant in Chicago) would join the Dolphins' staff. Well, it appears Slowik will not be joining Wannstedt's staff in Miami.According to the Dallas Morning News, the Dolphins will name former Cowboys assistant Jim Bates their new defensive coordinator in a press conference today.Bates had served as the Cowboys defensive line coach for four seasons before informing Dallas owner Jerry Jones on Friday that he did not plan on returning.The Dolphins are also expected to interview recently fired Dallas head coach Chan Gailey for the team's offensive coordinator position.
