Wisky should be happy if they get the wins against division opponents, because that would help if it comes to a tiebreaker for division title. 3-2 record with 2 wins against NU & Iowa would be huge for Wisky.
Averaging Massey, Colley & Sagarin, Iowa has played a tougher schedule than Nebraska in 2013 (6 spots) & 2015 (22). NU's was tougher in 2011 (19 spots), 2012 (45) & 2014 (19).
