Thank you..... It was bothering me that I couldn't think of the last one.
It's been exciting seeing the Packers using the 3-4 this year so far..... definitely a lot better than the previous scheme of vanilla man to man bump coverage all game long, with little of no saftey help for the CB's. This switch has added a few years to the careers of Al Harris and Charles Woodson..... not so much running man on man every play.
The Packers are playing a lot of 2-4-5 nickel defense this year so far when teams come out in 3 wide or any passing situation. They actually have it in the Madden play book for the Packers, and I use it a lot myself with decent success. In most of my games played it's the only nickel formation I use.
