I think that it gives KSU a slight advantage. I think we have pretty much seen what to expect from NU, and so the staff will have time to really dissect their weaknesses. NU isn't great against the run so that should hopefully be in our advantage.
Then considering the catastrophe yesterday was for us offensively, and knowing the NU will present a much tougher defense as a whole; Snyder will add some much needed wrinkles into the offense. After yesterday there cannot be anyway that they believe they can just stick the game plan offensively they've had so far.
This is quite possibly the last NU game for sometime, Snyder can't be willing to go down without mixing it up somehow. Plus, despite the fact Pelini has proven himself a halfway competent coach, given a week and half to prepare for them, Snyder should flex his coaching muscle some.
