Ughh? Defense anyone?

I keep seeing all of the McCown sucks threads, but where is all the talk about the defensive performance we have put on for 2 weeks now.  How do you as a defense let 2 backup QBs beat you? It started week one with the simple play action pass to the TE and this week it was the run and the pass, by a QB who has never started. I dont see how Lovie can continue to be as conservative as he was today and still expect to win. This defense does not have the front 4 ready to run the Tampa 2. We need to blitz and take chances(ala last year). Where's L David been? Is Lovie going to utilize him? Schiano did.......
