The defense has talent.  Middle LB position is a huge weakness.  Peko has been a stud addition. The reason for giving up 51 points is due to several reasons:

1. Defense just quit:  The defense has been the cornerstone of this team for the last couple of years and responsible for most wins.  In the past few weeks, realization set in on the defense that their best game is not going to translate into wins.  So they plain quit.  Complete lack of effort.

2. Schemes:  This team is used to playing Man defense and blitzing a lot under Wade.  VJ wants the team to play more zone & less blitzes.  That did not translate well.  

3. Coaching: Woods is a rookie coordinator.  He does not have a feel for the game and call plays accordingly.  Wade had a wealth of experience.  The defensive players can sense that they are being led by clueless coaches (VJ & Woods).  Translates into lots of penalties.

4. Lack of Player Development:  Walker was played in the wrong position during training camp.
