Plus, here's a some discussion board fodder I picked up from ExtremeSkins where some people are talking personnel.
Here's my quick take on the 3-4 in DC.
Pros: I like Albert at nose tackle. If he stays motivated he's got the size and quickness to be very disruptive.
Andre Carter has played OLB in a 3-4 before. He and Brian Orakpo would make a nice pair of bookend edge rushers.
London Fletcher can be plugged into any system and still be a tremendous leader.
Cons: There are no prototypical 3-4 defensive ends on the roster. And to think we missed out on Chris Canty and Igor Olshansky last year.
The defensive ends in a 3-4 have to occupy bodies and be strong against the run. Phillip Daniels in the only end who can do this and he's not much of a starter anymore.
There's no second middle linebacker either. HB Blades is a run stopper like Fletcher, but a 3-4 requires at least one of the MLBs to have the ability to penetrate. Dallas has one in Keith Brooking and look how far it's gotten them.
