"I am really excited to have Brian join our staff," Fisher said. "He is a well-respected coach in this league who has had success for many years at a high level as an offensive coordinator. We share the same philosophies on the offensive side of the ball and I think he is a tremendous addition to our staff."
"He brings an aggressive approach that I'm sure will benefit our defense and he has a wealth of knowledge that will aid our entire team," said Fisher, who was hired little more than a week ago.
The Rams replaced him with Fisher, who sat out the 2011 season after 17 years in Tennessee. He and Schottenheimer will have a franchise-type player in Bradford, the No. 1 overall pick in 2010, and the No. 2 overall pick in this year's draft. They also have a favorable salary-cap situation.
Schottenheimer has been here before: The former University of Florida quarterback was an offensive assistant on Dick Vermeil's staff in St. Louis in 1997, and later worked for his father, Marty, in Washington and Kansas City.
Williams, who has deep ties to Missouri and played at Northeast Missouri State, has put together seven top 10 defenses in 15 years as a defensive coordinator or head coach (Tennessee, Buffalo, Washington and New Orleans).
