ENGLEWOOD, Colo. (AP) - There are a few more lines around the eyes, each of them a mark of some lesson learned during a head-coaching tenure that lasted nearly a decade, had its share of success but ended badly for Jack Del Rio in Jacksonville.

Some things, however, haven't changed.

The Broncos defensive coordinator, now 49 and reunited with John Fox in the same role he had a decade ago in Carolina, is still a formidable presence whenever he walks onto a football field. And the schemes the NFL linebacker-turned-coach crafts still make life difficult for opposing offenses.

Denver's seventh defensive coordinator in seven years has the Broncos playing fast, and at a level this defense hasn't reached in a while. They are ranked sixth in yards allowed and 10th in points allowed.
