What is up with the poor play of the dline?

[PleaseCutStewart]

Unfortunately had to watch the team lose at Fedex today, but it amazed me how awful the dline looked. Somehow the Redskins only scored 23 points (probably because both teams' goal seemed to be to eat up clock), but seemed like the defense either gave up points or lost the field position battle on just about every possession after the first drive. The dline is just not capable of getting pressure rushing 4 (we really need to blitz more...). Even worse, the dline was just getting blown off the line and getting pushed 5 yards back, which let AP run about 5 yards before getting touched. Safety play wasn't good and blew the coverage on the Davis TD (not sure who was lined up on Richardson for his TD), but we can't really be surprised if the safeties suck. However, our defense is going to continue to get shredded if our Dline continues to play like ass.
