Defenses have also evolved to do this better out of a 4-3. You look at the best modern day 3-4 pass rushers and there is zero question about who is rushing and who is dropping into coverage. Pittsburgh is going to rush TJ Watt 99 times out of 100. The Cowboys are not going to move to a 3-4 and start dropping Micah Parsons into coverage a third of the time the way the would do an Anthony Spencer back in the day. It wasnt even uncommon for DWare to get 100+ coverage snaps a season.The success of a 3-4 pass rush is predicated on the surprise element of that 4th pass rusher. He could come out of nowhere. The defense is looking to confuse the O-line and their blocking scheme.
A couple of points here. 1)The 3-4 is not dying out, quite the opposite approximately 50% of teams use it as their base (and mainly the better DEFS i.e. Eagles, Ravens, Vikings etc) 2) If you can get 2 big-time OLB's it is very hard to predict who will do what. With someone like Parsons, he should not be rushing 99% of the time, but instead be more selective.Defenses have also evolved to do this better out of a 4-3.

A 4-3 crowd the LOS approach disguises who is rushing just as good if not better than the 3-4 looks do, plus you have better athletes on the field to get after the QB. This is a big reason why the 3-4 is starting to die out and is really more of a run defense front.
I say the 3-4 is dying out because even teams that run the 3-4 are using it less and less as 5 db formations have dominated snap counts. Even the 4-3 is dying out to some extent, but teams have still mimicked the 3rd LB in those 5db sets with other players. Also not sure that I would consider Philly or Minnesota a 3-4 defense...especially Philly. I only really see a few true 3-4 teams in the league right now....Pittsburgh, Baltimore, Carolina, Tampa....I might be missing a few? Denver, but they run a few different fronts, I think Minnesota is in a similar situation.A couple of points here. 1)The 3-4 is not dying out, quite the opposite approximately 50% of teams use it as their base (and mainly the better DEFS i.e. Eagles, Ravens, Vikings etc) 2) If you can get 2 big-time OLB's it is very hard to predict who will do what.

We will have to wait another year, but eventually I believe it will become clear this is the way to go, instead of this 'quick twitch' DEF that just simply is not built for play-off success. You have to stop the run first and players like Parsons and Ezeiruaku would thrive in a 3-4. We need someone to get in Jerry's ear and convince him about this.
