The point was that there are different ways to build a wining team. The supposition that we have to have guy who gets 15 sacks a year to have an effective defense is invalidated by the fact that the super bowl winners were middle of the pack in sacks and pressure--They succeeded because of a solid backfield and sound tackling.
The past four Super Bowl winners:
2016 - Patriots (Genius at coach, super genius at quarterback. Solid defense)
2015 - Broncos (Von Miller, 11 sacks; 7.5 sacks in 11 games)
2014 - Patriots (Genius at coach, super genius at quarterback. Solid defense. Bone-headed call by opponent.)
2013 - Seahawks (Legendary defense, Michael Bennet 8.5 sacks, Cliff Avril, 8 sacks)
I don't know if the past four Super Bowl winners exactly support your argument. Two of the past four Super Bowls have been won by the Patriots, who have the best quarterback of this generation and the greatest coaching mind of this generation.
In the Bronco's case, Von Miller registered more than 10 sacks that season.
In Seattle's case, their overall defense was just good, from the front line to the secondary. The defense led that team.
I don't think you could say in 2014 or 2016 that Dallas' defense led its offense. In fact, the talk was how our offense could help our defense via long, sustained drives.
I want to see our defense take prominence. Hopefully, these acquisitions can elevate this defense. Hopefully, Taco is our War Daddy. If not, then hopefully, we collectively can put a defensive squad on the field whose sum is better than its parts.
But it sure helps to have a 10-plus sack monster.
