The biggest concern is our rush defense vs. their rush offense. We're ranked 86th nationally in rush defense, our only major Achilles' heel. The tale of the tape:
Nebraska

Rush Defense - 86 (11)
Pass Efficiency Defense - 23 (4)
Total Defense - 51 (8)

I'm a little surprised to see their rush offense so low-ranked, but I think a lot of that has to do with Ball being dinged up. White is a more-than-capable replacement, and there's still every chance Ball plays anyway. I think our best bet in this game is to stack the box, sell out vs. the run, and try to put them in third-and-long, then kill whichever QB they put in the pocket.
Look at their stats through four games, and against so-so competition (#45 SOS) they don't rank in the top 25 in any category except Rush Defense.
Sell out against the run, keep a weather eye on Jared Abbrederis, and we should be able to outscore them.
