After just one season, defensive coordinator Bates out in Denver

Denver Broncos head coach Mike Shanahan and defensive coordinator Jim Bates came to a mutual agreement to part ways Tuesday.

Bates, who was a head coach candidate when he was with the Green Bay Packers, was hired last year to turn around the Broncos defense. But the team went backward instead of forward, finishing 19th in overall defense and 30th against
the run, drops from a year before when coordinator Larry Coyer was
fired. Rather than accept a reassignment to the staff, Bates decided to
walk away with two years remaining on his contract. Bates and Shanahan met Monday and came to a resolution late Monday night.

"I had the opportunity to stay," Bates said in a written
statement. "[Shanahan] has been very fair with me, and
the final decision, for the Broncos and for me, was to step

The Broncos signed Bates to a three-year, $3.9 million contract last year.

Bates, whose title was assistant coach-defense, had success with
his system with the Packers and Miami Dolphins, but the
Broncos were unable to master it.

A few weeks into the season, the Broncos were allowing nearly
200 yards a game on the ground and decided to ditch the hallmarks
of Bates' ballyhooed system, replacing their big, beefy interior
linemen with smaller, quicker tackles who could pressure the passer
and putting safety John Lynch in the box as an eighth defender
against the run.

Things improved but the progress came haltingly and the Broncos
(7-9) ended up allowing 409 points, fifth-most in franchise
history, while posting just the second losing record in Shanahan's
13-year tenure.

Bates said he was "very saddened that things did not work

Team spokesman Patrick Smyth said the Broncos would have no
comment beyond Bates' statement. Shanahan has scheduled his
season-ending news conference for Thursday, when he's expected to
announce that Bob Slowik will assume Bates' duties.

Slowik was promoted to defensive coordinator last year after Bates was hired as assistant head coach in charge of the defense. Slowik was also in charge of the secondary.

Slowik served as defensive boss once before, for Mike Sherman in Green Bay in 2004. That didn't work out well and Slowik parted ways with his good friend and joined the Broncos the following season.

Some players suggested Bates' system didn't take because there were so many new faces on the line and others blamed too much holdover from Coyer's philosophies.

"I just don't think we had any consistency or any confidence at any point in ourselves as players or in the scheme that we were running," defensive back Domonique Foxworth said last week. "I think it's important that we build that into the next season, that we find something that we're good at and we stick with it from start to finish."

Defensive lineman Kenny Peterson, who worked for Bates in Green Bay and benefited from the change in personnel and philosophy as the season progressed, said: "It was unfortunate it didn't work here because I like his system. He has a good system, it's proven, it's tested."

Linebacker Nate Webster said too much youth put the Broncos in a pickle, but Foxworth suggested the problems stemmed from the scheme actually being a hybrid.

"It wasn't 100 percent commitment, I don't think, from Day 1 to the new scheme," he said.
