Ok, explain to me how not being aligned with anyone is good for ISU? Will ISU get a sweetheart deal on NBC like ND has? Who do we play in football? Is USC going to schedule us as a non conf opponent? How many major schools are going to schedule us for home and homes? Iowa and who else?
For the beginning of the season I would imagine anyone who is interested in a decent opponent for conference play, but not a guaranteed loss. Someone that doesn't want a team that will drop their Strength of Schedule.
Notre Dame very well might.
We got a home and home from places like Army and the other academies.
Missouri or Minnesota might be interested from a fan interest perspective. I would guess any of the old big 8 schools would be interested once in a while (not necessarily yearly).
Someone like Boise State who needs to get a boost from non conference games. They currently have Wyoming and Virginia Tech scheduled for non-conf. I'd say we'd fall in that range.
We don't get a sweetheart deal like ND has because we don't have the national fanbase, however we would also not have to share our TV revenue with a conference when we do make the TV. Look at what FCS schools get for coming to play somewhere big.
The fact is it's just too hard to know what would happen unless you tried it. I don't believe it would be the guaranteed death sentence you are making it out to be. I also don't think it's a guaranteed success story.
