I noticed a lot more variations of defensive packages under Rivera last year than we ever saw out of John Fox. Everyone knows we employed the 3-4 at times but we also had a few other looks that intrigued me as well. The "Buffalo Nickel" Much like your standard "nickel" defenses this package uses 5 defensives backs but instead of the typical 3rd corner substituting in for a linebacker we used a third safety, mainly Jordan Pugh. The Giants apparently used this formation more than anyone else.
