Defensive strategy for the Steelers and a pb

Ok so i have decided between the vikings and the steelers and i have chose the steelers so i need help on a strategy for the steelers on defense as well as a playbook please. thank you in advance

personally i'm still trying to decide between the nyj and ne d playbooks for the steelers. as for strategy, you have to be aggressive and mix up your looks to confuse the offense. blitz when you see an opportunity though but you can't do it every down or your secondary will get absolutely torched if your opponent can pass the ball. throw off the offense and dictate to them what they're going to do by forcing incorrect pre-snap reads.

right now i'm leaning heavily towards ne d pb because i love the 1-5-5 prowl with the steelers d, but it sure would be nice to have odd split with them too, which is making me still consider the jets d pb.
