Honestly, Nebraska beating Iowa seems the least likely ... I think we come out rejuvenated with how we played at Michigan and beat Northwestern methodically. I also think that if Indiana plays like they did against MSU, anything is possible in a rivalry game at home. Purdue has also shown the capacity to not show up (see Iowa loss). However ... it seriously seems like the Iowa football program owns Nebraska in a way that is practically like being in their heads.
#16 Iowa 28, Nebraska 21 in Lincoln (UNL up 21-6 before collapsing in the fourth quarter and giving up a TD with 2:58 left to lose)
#24 Iowa 26, Nebraska 20 in Iowa City
#17 Iowa 27, Nebraska 24 in Lincoln (Iowa game-winning FG with :01 left)
Iowa 31, Nebraska 28 in Iowa City (Iowa game-winning field goal as time expires)
Iowa 56, Nebraska 14 in Lincoln (game tied 14-14 at half before a complete UNL self-destruction)
Iowa 40, #17 Nebraska 10 in Iowa City (costs UNL a chance at winning the West)
#4 Iowa 28, Nebraska 20 in Lincoln (4-point game with 6:43 left before UNL gave up a 68-yard TD run)
I'll be rooting hard for ole Nebby, but I unfortunately have next to zero faith they can march into Iowa City and win, haha.
