The Giants won the SB in 2011 using their Nickle (4-2-5) Defense as their base D. Maybe it's just me, but in this new day and age of the NFL (all passing with a dash of running), this seems to be one of the most effective ways to play these spread offenses. And, oddly enough, if Dallas were to sign Huff, they would have the pieces to implement this. My version would be (of course, if everyone was healthy):
LE - Selvie
DT - Hatch
DT - Hayden
RE - Ware
SS/WLB - Church (playing him closer to the line would do nothing but help him - if they go to zone, he should be much better playing the flats than covering deep)
MLB - Lee
SLB - Carter (SHOULD be better matched up against TE's vs. RB's)
CB - Scandrick/Claiborne
CB - Carr
SS - Wilcox
FS - Huff
Getting your best 11 on the field should be the goal of any team.
