The marketplace has knocked this total down a little, but not enough. There is still value going Under given the teams and conditions.
Iowa surrenders the fifth-fewest points in the nation at 12.2 per game. The Hawkeyes have held eight of their 11 opponents to season-low point totals. The Hawkeyes, though, lack a dynamic offense. They rank 102nd in scoring at 23.5 points. So it's not a shock the Under is 8-1-1 in Iowa's past 10 games. 
Nebraska doesn't make many big plays either. The Cornhuskers are 78th in scoring at 28.4 points. 
This is a rivalry matchup. The teams play for the Heros Trophy so intensity should be up. 
Another key factor for the Under is weather. The forecast is for rain and 15 mph wind.
