The Husker defense says they’re ready for the bright lights…by what game are we allowed to say they’re ‘back’?

It’s been the message of Fall so far that the defense has made strides, and Tuesday’s post-practice media session continued that vibe. But when assessing if they are truly better, and possibly even WAY better, what’s our barometer test for them? Can’t go off of the South Alabama game…do we have to wait until the Ohio State game (game 5) before we can assess if they’re a good defense, or can we assess it after Colorado/Northern Illinois?
