Bears defensive coordinator resigns

The intrigue: Head coach Matt Eberflus announced late last week that Williams would miss the game in Tampa and that he'd step in for defensive play calling.

• When asked about the absence Wednesday at Halas Hall, Eberflus said he couldn't give a timetable for Williams' return to the sidelines.
• A few hours later, Williams' resignation was announced.

What they're saying: "I am taking a step back to care for my health and my family," Williams said in a statement.

• "I value the NFL shield and all that it stands for and after taking some time to address my health, I plan to come back and coach again."

Context: Williams came to Chicago to helm the defense last year under first-year head coach Eberflus.

• Williams was a defensive backs coach with Eberflus in Indianapolis and has coached in the NFL since 2001.

Catch up fast: Last year, the Bears had one of the worst seasons in franchise history, with their defense ranking toward the bottom of the league.

• After an offseason of adding free agents and rookies, analysts and fans were optimistic about this year's squad.

Yes, but: The Bears have had a rocky start, while the defense has only one sack and hasn't forced any turnovers.

What's next: The Bears have yet to name a successor, but coach Eberflus could call the defensive plays again this Sunday in Kansas City.
