First section is a decent look at the defensive debate currently on-going in the NFL. Some tidbits: "Tactics matter, but players are more important. Give me a 4-3 defense with good players over a 3-4 with poor players any day of the week." "And consider the Washington Redskins. Using a conventional 4-3 with little blitzing, the Skins finished fourth in defense in 2008 and 10th in 2009. This year, seeking to "make plays" on defense, Washington switched to a blitz-a-rama 3-4. The Redskins are now last in the NFL in defense, and just surrendered 30 points to the hapless Rams. Not much of a testimony to the supposedly magical 3-4."
