... the lack of turnovers by this defense is a major factor in why this team struggles.

Total number of turnovers by year:

2012 16 ----- N.E. currently has 39!
2011 15 ----- N.E. had 34!

2010 35 (Superbowl)
2009 22
2008 29 (Superbowl)
2007 25
2006 29
2005 28 (Superbowl)
2004 32
2003 25
2002 36

Two straight years without getting to at least 20 turnovers.

This trend has got to change.
