I do know that New England, Pittsburgh, San Diego and Dallas all played the 3-4 and won their divisions this year. I am not sure if anyone else played it or not besides Baltimore and they've had a great D until this year. As we did when we played it.
Dasher I have seen both systems used with great success. It's my opinion that it's better to be in the minority of teams running a particular defense, than in the majority. When you are in the minority there is less competition for players and teams are less used to facing it.
Here are a couple of more good articles and the 3-4 and the 4-3
