I think ISU will find it's way to 5-7 somehow. UNI, SJS, and KU should be wins. Tech, WV and KSt at home later in the year when hopefully the team is more in synch with new staff and systems - get 2 of 3 there. Maybe they bag Texas or Iowa on the road, although not likely imho. I think they have an outside shot at a bowl game. They weren't as far away from competent last year as the record looked.
The O-line is THE major concern as others have stated. If the staff can assemble anything like a decent line, the other parts are there. The defense might be really salty. Stay tuned.
As for Iowa, I expect they should be better as a team (more experience) but have a worse record. They really caught a lot of breaks last year.
Just looked at their schedule, god almighty. Anyone with a pulse they have at home! NW, Wisky, Mich, Nebby. Their road games are a chum bucket of Ill, Rutgers, Minny, Purdue, and Penn St. And they avoid the best 2 teams in the conference AGAIN. There just aren't any games where you would pencil in "L". But there are some tossups. Nine or ten wins seems likely. That's my 5 minutes of in-depth analysis.
