We are currently in the midst of what is easily the worst season defensively of the John Groce era.  For example, Ken Pomeroy's site has us ranked as the 256th best defensive team in the country based on the AdjD stat, compared to #165 in Groce's first season, and #111 last year. 

One big difference between this year and the first two years is the loss of Chris Holtmann from the staff.  When Groce was first hired I remember Holtmann being trumpeted as a defensive guru, so I can only wonder how much of our defensive regression this year relates to Holtmann's departure?
