The Broncos have lost defensive coordinator Dennis Allen to Oakland, where he will take over as their new head coach. Denver will again be searching for someone new to run their defense and will start the 2012 season with their seventh DC in as many seasons. Allen had been an assistant for the Saints under DC Gregg Williams before John Fox made him a coordinator for the first time, and like Williams he showed himself a confident and aggressive coach unafraid to dictate terms to opposing offenses.
There's been some speculation that ex-Jags coach Jack Del Rio is a possibility, and Dave Krieger says current Denver LB coach Richard Smith is another option. Del Rio was the Carolina DC for one season under Fox in 2002 before taking the head job in Jacksonville, while Smith has been a DC in Miami (2005) and Houston (2006-08).
