First of all, Rahmir dropped a pass on 1st & 10, with Nebraska leading Illinois 9-6 at 7:24 in the 2nd quarter. Rahmir wasn't going to score on the play, the safety was 3 steps from ending Rahmir's life had he caught the ball. It should've been a nice 18 yard gain. This is not from memory, it's still in the DVR of my YTTV account so I went back and watched it.
On second down Grant did his usual job of losing a yard by dancing laterally instead of getting the 3-5 yards that was easily there had he run through the hole that was there. Then, on 3rd & 11 Mickey decided to throw deep from our own 30 knowing that Illinois would bring pressure. Oh, and he called a timeout to make sure Walters had plenty of time to dial up his best blitz. He could've (should've) stayed conservative in 9-6 game and ran the ball and punted, but instead ran Grant on a pattern out of the backfield and left no one to block the linebacker that ended CT's season. Whoever called that play got CT murdered. And... I'd be remiss to not mention that CT was throwing off his back foot to a receiver that wasn't even open.
Nebraska sucked last year. There was no "one play" that was the fulcrum that the season balanced on. Every QB that played last year got murdered because the o-line was terrible and the play calling was terrible.
