I think KSU can keep it close early. Thomas will get some yards while he's still fresh. I'd put him down for just over a hundred yards on 25-30 carries, right around 4 per carry. Solid, respectable, but unspectacular. Thomas is usually able to make the first guy miss or break his tackle, but against Nebraska there will be three first guys getting to him at once, so a lot of his 7 and 8 yarders are only going to be worth 3 or 4. Nebraska will put KSU into several third and 5+ situations and KSU won't be able to convert. Nebraska will dominate time of possession and KSU's weak defense and lack of depth will get exposed.
Halftime score: Nebraska 21-10.
Final score: Nebraska 35-10.
