All I'm saying is if they're going that way, then fit the puzzle pieces into a coherent picture. As previously discussed vis a vis PIT and SF with their smaller lines, it can work if you have fast, physical and skilled linebackers. We don't have those guys, so they should go get a couple. Or reload the big body supply and follow the previous path.
Neither approach is easy. They're opting for the latter it would appear. The flavor of the decade in college football is SS converted to LB...light, fast guys who are not afraid to hit, with a safety's understanding of defenses (fast, physical, skilled). It may just be a matter of fitting the scheme to the available talent; the Packers always bemoan how hard it is to find athletic big bodies.
However, the idea of going small on the D-Line with the incumbent back 7 largely intact is a recipe for disaster. Teams that run the ball well will keep us in short yardage and base-D all day.
