The Broncos hired Jack Del Rio as their defensive coordinator on Friday, replacing Dennis Allen, who was officially announced as the Raiders' head coach earlier in the day.

Del Rio spent the past nine years as the head coach of the Jaguars, but he was fired November 29, 2011.

Prior to working in Jacksonville, Del Rio was the defensive coordinator for the Panthers, where he worked with John Fox. Now the Broncos head coach, Fox felt the two would work well together again.

"We are thrilled to be able to add such a well-respected defensive coach to our staff," Fox said on the team's Twitter account. "He was an integral part of our turnaround on defense during my first year with the Panthers in 2002. His defenses with the Jaguars have ranked among the NFL's best, and we are excited he's a Bronco."

The way we see it

Del Rio will have a lot of defensive talent to work with in Denver, including top pass rushers Elvis Dumervil and Von Miller. He will, however, have to improve the unit, which allowed 40-plus points four times in the regular season and once more in the playoffs.
