Bates left the Packers on Jan. 16 in an amicable agreement with new head coach Mike McCarthy. Bates' assistant, Bob Sanders, who coached the team's defensive ends last year, was named coordinator by McCarthy five days later.
New Bills head coach Dick Jauron hired Steve Fairchild to be his offensive coordinator on Thursday. Fairchild, 47, was the St. Louis Rams' offensive coordinator the past two years and is familiar to the Bills. He was Gregg Williams' running backs coach in Buffalo in 2001 and 2002.
Bates, 59, got good reviews for his work with a depleted Green Bay defense this year. The Packers ranked seventh in total yards allowed. In 2004, they were 25th.
Bates was defensive coordinator for Dave Wannstedt in Miami from 2000 to 2004. He was interim head coach for the Dolphins late in 2004 after Wannstedt stepped down. Bates also has worked in the NFL for Cleveland, Atlanta and Dallas.
At this point, there are only two other possibilities where positions may open for defensive coordinator in the NFL - Houston and Oakland. The Texans named Gary Kubiak as their new head coach Thursday, but he said that he'll take some time name his new staff. The Raiders are the only other team in the league without a head coach.
