I dont think there is any doubt that the D-line is what made our secondary so good. In football everything starts up front. With a great D-line it makes everyone elses job easier. Without a good push the secondary is left out to dry because eventually someone will get open. Also with the Dline we had, we didnt have to blitz which allowed everyone else to remain in position. Suh often took on 2 lineman and in some cases 3, which made it like playing 11 on 8/9. Our DB's were good but they looked great because of Suh and Co.
