Briggs, Harris, Vasher, and McGowan (over Chris Harris) are better. Urlacher, Tillman, Ogunleye, and Alex Brown are at least as good. Mike Brown, the other DT (vs. Tank or Ian Scott), and Hillenmeyer are probably slightly worse. The backups (D. Manning, Idonije, Williams, Payne, Anderson) are better than the 05 backups which included Azumah, Mike Green, Todd Johnson, Boone, and Michael Haynes among others. I don't think it's a stretch to see this defense being better than the 05 version. 05-08 Briggs=Briggs Urlacher>Urlacher Hillenmeyer=Hillenmeyer Ogunleye=Ogunleye Alex Brown>Alex Brown Tommie Harris Tank Johnson>Dusty Dvorchek Mike Brown>Mike Brown Chris Harris=McGowan Vasher=Vasher Tillman=Tillman Secondary depth Line depth>Line depth Just my opinion...it could be close to '05 levels, but then again people change as they get older, schemes change or quickly get outdated by opponent adjustments, etc.
