With Steve Spagnuolo going to the Rams in 2008 and an ineffective Bill Sheridan in 2009, the Giants have had to search for defensive coordinators each of the last two seasons. With Perry Fewell finished interviewing for head coaching jobs that are no longer vacant, it's almost guaranteed that for the first time since the 2007 and 2008 seasons that the Giants will have the same defensive coordinator for two consecutive seasons.
Many people feel that "The Rooney Rule", where teams have to interview minorities for potential coaching candidates, strikes again. I understand that the NFL is trying to promote diversity, but this is ridiculous. Perry Fewell has interviewed for over 7 head coaching vacancies in the past several years, and hasn't gotten one consideration. I am glad he wasn't hired so the Giants don't have to go out and find another defensive coordinator, but don't waste his time.
Back to the man himself. I'm not sure what to make out of Perry Fewell. He turns the 30th ranked defense from 2009 and turns it into the 6th ranked a year later. That would seem like an incredible feat, but not for who the Giants have. Adding Antrel Rolle and having a healthy Kenny Phillips was going to add to the defense, and it seems that with that defensive line, the secondary only has to be decent. Perry Fewell did a good job of not getting too fancy, and let his players do the work. I don't know if he's a brillant defensive coordinator, but he does have the players to make him look good.
