there was no pass rush? I seem to remember Patterson in the backfield quite a bit against Michigan, and Kudla during both games.
I don't think the 05 defense is quite on par with the 02 one, however the 05 defense probably faced at least three better offenses (during the regular season) than anything that the 02 defense faced. Yes I remember the miami game, but the shutdown factor was similar during the 05 bowl game vs ND (walker is no mcgahee, but most other positions were pretty stellar at ND).
