I don't know enough about defensive scheming to comment specifically on whether Wanny is or isn't doing the right thing, and I don't think the broadcast of the game allows fans to see the whole field enough for anyone that does know to comment accurately. In saying that a large part of the game is passion, emotion, and interest. This is evident in the playoffs when you see defenses ramp up the intensity and in some cases play better than they have throughout the year. I know that the money these guys made should be motivation enough, blah blah blah. We have talent and you can't say that in order to be an NFL or college coach you must know an awful lot about football.
To me the driving force of an NFL team is the QB. I'd argue all day long with anyone that if we had a QB worth his salt, this team would be very good. I know it's been said at nauseum, but it's all this team needs.
