Honestly, schedule strength will be the least of our worries. If we're up for a potential at large BCS bid, our biggest obstacle will be our small fanbase and lack of national appeal. Why do you think Ohio State went to the BCS last year over Boise State? Boise State was rated higher, but OSU was chosen because of $$$. They are one of the biggest TV and ticket draws in the country.
Especially if we play both D-1AA opponents in September (as it appears will happen), it will rarely get a mention. Again, Texas Tech played two 1AA teams last year in September, but by mid-October no one ever mentioned it. All anyone remembers is what you do at the end of the season.
Now, hypothetically if we were to go undefeated, and two other teams were to also go undefeated, that's the only situation where I could see it being brought up, but what are the chances of that happening? And honestly, with the last three BCS champions coming from the SEC, I think they'd have a really hard time leaving out an undefeated SEC team.
