The following is pasted from Wikipedia's Chuck Pagano entry pre-Indy head coaching job...
I know there was some discussion of this when he was hired, but does anybody feel like having a guy with only one year of DC experience could be a problem? It is a curious factor that he has so little DC experience, yet replaces maybe the most tenured DC in the league. Along the same line, last year's coordinator was renowned for his creativity in getting to the passer and this year's has arguably almost no experience working in that area.In 2001, Pagano joined Davis in the NFL as secondary coach for the Cleveland Browns. In 2003, he helped the Browns tie a franchise record for the fewest passing touchdowns allowed with 13. In 2001, the secondary accounted for 28 of the Browns' NFL-high 33 interceptions, and, in the same season, rookie cornerback Anthony Henry led the league with ten interceptions.
After leaving Cleveland in 2004, Pagano spent two seasons as the defensive backs coach of the Oakland Raiders. In 2006, the Raiders allowed just 151 passing yards per game and 285 total yards per game. This ranked them first and third in the league, respectively.
Pagano was named to John Harbaugh's initial coaching staff with the Baltimore Ravens on February 12, 2008. He served as defensive secondary coach for three seasons. He was promoted to Defensive Coordinator on January 18, 2011, succeeding Greg Mattison who accepted a similar position at the University of Michigan. That year, Pagano's defense finished 3rd in both points allowed and in yards allowed. They finished 13 in takeaways and 2nd Rush yards allowed, but Baltimore's defense has always been known for its ability to stop the run. Pagano drastically improved the pass defense going from 21st in passing yards allowed to 4th. They improved from 9th in passing touchdowns allowed to 1st in the league. The defense also came away with 17 interceptions. Pagano is known for his ability in secondary and ability to stop opposing teams pass attack.
Obviously, it appears that he should be a boon for the DBs, particularly our rather experienced group. But at the same time, he's really going to be leaning on his front 7 coaches, since that's not his area. That those front 7 guys have a reasonably amount of experience should help.
