Alright, so 1) I'm no Mathlete and 2) This may mean squat come Saturday, but here goes...
We've all been preached to about how our mighty Dilithium powered offense hasn't faced any REAL tests yet, with the inference that MSU will somehow be our first real litmus test. In particular, our first challenging RUN defense faced.
I've also read a few casual at best mentions, acknowledging that our past opponents defensive rankings may be slightly inflated for having played against said dilithium power. Nowhere though, have I seen anything that quantifies this effect, hence my attempt.
Looking at Notre Dame and UConn (chosen because they've played the toughest schedules of our ooponents to date), I factored out the numbers that UM hung on them, both in terms of total defensive yardage allowed, and rushing yardage allowed:
Notre Dame moves from per game avgs of 401 total yards, 153 rush yards down to 368 total, 119 rush.
UConn moves from per game avgs of 338 total yards, 162 rush yards down to 304 total, 130 rush.
For comparisons sake, MSU is currently at per game defensive avgs of 328 total yards, 101 rush yards. While it would appear that MSU does indeed have a better "D" (and specifically, RUN D) than we've seen thus far, I'd argue that their own numbers have been skewed.
Two of their opponents rely heavily on the passing game: Florida Atlantic's offensive total yards to date have been 922 pass yds to 291 rush yrds (45 yds vs MSU). Western Michigan's offensive totals to date have been 1100 pass yds to 307 rush yds (85 yds vs MSU).
In my opinion, we're going to run all over Sparty, Greg Jones or not. MSU will get their points, but I I'm not worried at all about us, I think they're a pretender.
