For Iowa:
1. Notre Dame
2. Air Force
Notre Dame was a traditional rival, but only old people remember it. Air Force because my brother-in-law and sister live in Colorado Springs, and it would be a great annual event. I would like to see Iowa play a service academy occasionally. Iowa played Air Force once in the 1950s right after the academy opened. I don't think they played another service academy, unless it was Iowa Pre-Flight during WW-II. Not sure that would even qualify.
For FSU:
1. Notre Dame
2. Iowa State
3. Purdue
4. Wisconsin
5. Minnesota
6. Northwestern
More opportunities to see the 'Noles play in the Midwest.
