A few things:
1. Denver Run D may be adequate, but as many others have pointed out, it helps your Run D #s when your passing offense gets you up by 2-3 scores in the first 20 minutes. Changes teams' plans, and they stop running the ball and start playing catchup. IMO Denver is probably a mid-level Run D.
2. To the folks saying "don't go back into Seattle sports mode," I've been on Cloud 9 since Sunday. No angst here. But I live in the midwest and see local/national media, and it's tough to ignore how little credit is being given to us for the win. I don't think they're "haters," but people wanted to see a nailbiter and they saw a blowout. People here are saying it was a "sh1tty" game, and all the talk I hear is not about how we won, but about how Denver lost. Hard to ignore how much of the country thought of them as the good guys. But I still enjoy it.
3. Agree on the run blocking, but Marshawn is making it harder. At the end of many games we love him for it, but Lynch has stopped powering through the open gap for a guaranteed gain of 3+, and is now trying to make his own holes by running laterally. Add that to poor run blocking, where defenders are getting into the backfield in under 2 seconds and he's getting stuffed behind the LoS on half his run plays.
