1.  No effective pass rush (been years since we had one)
2.  Cornerbacks who seem to always have their back to the ball
3.  Miserable, unimaginative offensive play calling (no real 3rd option anymore)
4.  No running game, especially when they need to kill clock time
5.  Inconsistent tackling
6.  Not capitalizing on turnovers
7   Unable to make gametime adjustments (a former hallmark of the pats)

I'm really hoping the defensive problems are youth related because if it's a lack of talent, intelligence or a combination of those 2 then we may truly be witnessing the end of the consistency we've all come to know.  Here's to hoping these guys can eventually "get it" and return the Pats to "swagger" status...we'll see
