9 of the top 14 defenses last year, according to NFL.com, were 3-4 defenses. Including one coached by a familiar face whose probably still belly laughing at our mistake.
If you listed the best defenses of the last 20 years the vast majority would be 3-4 defenses.
10 years ago. Now. It's a superior scheme.
It's a superior scheme because it's more flexible. It's much easier to find rush linebackers than it is a down DE who can get to the QB but also hold up in the run game. A 3-4 defense is more balanced. It's harder to block. A 4-3 is much more predictable.
This is why the 3-4 came about. It was about creating edge pressure. The lack of DE's who could do it. It's as true today as it was then. It's always easier to find a rush LB.
Most of the league is not running the 3-4. Half the league is. But there is simply a bigger supply of players capable of filling the rush LB role than there are quality pass rushing DEs.
It doesn't take much common sense to figure out if you get a DL off the field and replace him with a much more athletic LB, you're going to defend the read option better. Not that that is really meaningful as that's a passing fad.
It just boils down to what makes the QB and his protection work harder and to me it is definitely the 3-4 look. That was one of the worst mistakes Jerry Jones has ever made when he got rid of Rob and that scheme.
Nobody's saying you can't have a dominant 4-3 defense. Of course you can. But overall you will find a better success rate with the 3-4 than you will the 4-3.
You’re using NFL.com’s ‘defensive rankings’ which are based on yards allowed. This has been proven to be a faulty and incomplete look at how to accurately measure the effectiveness of a defense. That’s why I use FootballOutsiders.com which factors in the quality of the offenses faced, down and distance situations, etc.
Dallas used Wade’s 3-4 in 2010 and 27th in Defensive Ranking according to FO.com. And it was worse that year when Wade was coaching than it was until Garrett became the head coach. For all of the ‘belly laughing’ Wade is allegedly doing, he should have worried about his own defense when he was here because it got him fired in the end. And it’s not like he doesn’t want to be a HC as he tried to apply for the Houston job but they told him ‘thanks, but no thanks.’
Even after we fired Wade, we still stuck with the 3-4 and finished 16th in Defensive Ranking in 2011 and 23rd in 2012 (again, according to FO.com). Wade’s Houston defenses were really good, but fell to 18th in 2013.
You’re making a grandiose assumption in that almost all of the best defenses in the past 20 years were 3-4 schemes. From 1995 to 2008-ish, most of the schemes in the NFL were 4-3. Jimmy showed that you could use smaller, but faster players to your advantage. It was something that the pros didn’t think would work in the pro game. Dungy created the 4-3 Cover 2. And then Kiffin created the Tampa 2 with Over and Under looks and soon almost everybody was using some form of 4-3 from 1994-ish to 2008-ish. In that time you had a Ravens 2000 defense which used the 4-3 exclusively. The Giants had a dominant defense that year and were also a 4-3. Kiffin’s defenses ranked in the top-10 in FO.com’s every year except for 2 when he was in Tampa and they were a 4-3. We also had Jim Johnson’s Eagles defenses and Lovie Smith’s early Bears defenses…each 4-3 schemes. The real long-standing, dominant 3-4 defense was the Steelers. The Patriots 3-4 scheme was really great for a few years, but then became their weakness.
And if the 3-4 is ‘superior’ because it creates a great pass rush, then why did the Giants in 2007 have the most dominant pass rush in the past 10+ years and used…a 4-3 scheme?
I don’t think either scheme is superior. But as Landry stated, schemes end up evolving because teams try to figure out ways to beat it. And from a pure supply and demand standpoint, that plays a huge factor as well.
Teams started to beat the 4-3 Cover 2 by getting athletic tight ends and fast slot WR’s to go deep down the seam and attack the MLB having to drop deep in coverage. Teams went to the 3-4 to help confuse adept QB’s and help stop the run. So, teams started using more shotgun and 3 & 4 WR sets in order to force one of the edge rushers to have to drop back in coverage. And for now, it’s working.
So now the majority of the league plays a 3-4, it’s providing 4-3 teams with an advantage in the draft because they don’t have to compete with as many teams for the same pool of players. And it allows them to play against shotgun and pass happy teams and get their 4 best down linemen to rush the QB.
Eventually teams will follow the Seahawks model. Especially if Dallas becomes successful with the 4-3. It’s a copycat league. And then as more teams go to the 4-3, there will be some coach that goes back to the 3-4 and figures out how to add some new twists to stop whatever new offenses are doing from a schematic and personnel perspective.
There is no superior.
