This is somewhat simplistic, since I also know the importance in coverage the Mike is in a Tampa 2, and the DE to the pass rush, as well as a cover corner. And it takes all on defense to make a team D a winning D. However, I really take a look at 3 guys first, then those other 3 above- The Undertackle, then the Will, and finally Free Safety. Interestingly enough, Booger McFarland was the NT in both of these D's. Here's the D from their respective SuperBowl winning teams through my first look lens: Tampa- UT- W. Sapp, Will- D. Brooks, FS- John Lynch. Wow! then DE- S. Rice, (Wow!) Mike- S. Q
