The D given it has no real play makers without Revis has done a great job this year. We have a very young DL that is playing very well and some good DB depth. If we had a QB that could drive the ball and not give up 3-4 bad turnovers a game we'd still be a top 5 D. If we pass the Bears and Zona I dont see that as being a sham stat either. Sacks are sexy but you don't need then to have an effective D. All the talk of not getting pressure and the passing D still has top 5 #s. Our rushing D has just been horrid because none of our LBs can catch a RB anymore.
Add an OLB or 2 and this could very well be an elite D the way they are playing. LB talent in general is the biggest weakness right now. Add one guy that can add outside pressure and stuff the run and we are elite again. The backbone is there we just need that trigger man to put it together. It is not like the whole D needs to be blown up. Dump the old guys and improve. The O looks much harder to fix.
