Iowa: 60-36 regular season (.625) / 61-42 overall (.592) / (1) season > 9 wins / 1-5 in bowl games.
NwU: 57-39 regular season (.594) / 59-42 overall (.584) / (3) seasons > 9 wins / 2-3 in bowl games.
The stronger program is a debate. That Iowa and NwU are nearly exact peers is indisputable. If that's not disturbing enough, NwU is the clear winner when you factor in the intangibles, like, academics, resources and facilities, fan support, and generally doing more with less.
I dispute the resources, facilities, and fan support part. jNW is better in most areas of academics most would say, I cant say because I have never measured it, but it is what I think is correct. I think you mean athletic resources and facilities and in that case Iowa brings in more money and has better facilities. Fan support you have to be kidding as there are usually only about 30K jNW fans at their home games and I have heard they do not travel well to bowl games. Tell me what I am wrong about here.
