2. Dom Capers
Tenure: 14 years, average rank 12.6
Teams coached: 1992-94 Steelers, 1999-2000 Jaguars, 2007 Dolphins, 2009-present Packers
Capers' Packers defenses have been extremely inconsistent, going from second in DVOA in 2009 and 2010 to 25th in 2011 and then back to eighth in 2012. His Steelers defenses were stronger, ranking first overall in both 1993 and 1994. Capers also has seven years as a head coach, with Vic Fangio as his defensive coordinator, which are not included in the average rank above. His Panthers had the remarkable accomplishment of ranking
fifth in defensive DVOA as a 1995 expansion team, but the Texans had below-average defense in all four of the years Capers and Fangio were there.
