The biggest advantage this defense has imo is that it is built for the times. In 2015 the league was still a pass heavy league but we had very little investment in our DBs. We could obliterate the run game and we could rush the passer, but if we didn't get to the QB quickly enough, guys would be open downfield.
This defense has been built to blanket receivers and aid the vicious pass rush. Half the team can drop back in coverage effectively. Burns, Reddick, Shaq etc. And then we finally invested in the secondary. Horn looks like a legit lockdown CB in the making, Jackson continues to improve, Chinn we already know is elite and can play pretty much anywhere and we haven't even seen the defense with Bouye yet.
And lastly, we have a DC who is damn creative in what he does with all of our versatility. Ron Rivera knew how to build a defense but he was one of the most predictable coaches in the league and so you always knew sort of what we would try to do. Snow has a bunch of players than can be moved all over the field. And he isn't afraid to mix up what they are doing and keep the opposition guessing.
It is too early but IMO there is a real chance this defense could become our best ever. Maybe not this year, but in time. I mean half this defense is playing on rookie deals currently and they are our better half of our squad. The potential this unit has is pretty staggering.
