I disagree it's "totally different". I think that's blow way out of proportion. I think stopping the run and getting into 3rd and long situation is still the way to win football games. It's still about getting the QB off his spot, smacking him in the mouth and sacking him on occasion. It's about beating the guy in front of you, not running around him. I don't Seattle plays "soft" and I don't think Seattle is forcing speed over toughness. I don't think San Francisco or Cincinnati (two very talented defensive units) are following this "smaller, faster, nickle" talk. Cincinnati has a MLB that runs a 5.0. Their front 4 is dominating with power and ability.
We will see if adding Mitchell and Shazier make up our very week and very thin D-line. The proof is in the pudding. We'll have to wait until the games are played.
I agree which is why I still would under stand a Nix pick. Forcing teams into predictable down and distances is key. I do think because we play a 3-4 its harder for us to combat what teams are doing. The key to our run defense has to come off the field when teams spread us out. The bengals not so much. I dont think they have to take Atkins or Peko out when teams go spread so they are still able to contain the run. San Fran already has what we are now attempting to do two middle linbackers who can cover just as well as they run stuff. So they are fine against spread offenses.
