Dropping a game certainly is an option, but are we really going to see non-conf BCS opponents after we go to 9 non-conf games? I don't know the answer - I haven't seen it discussed much, but I'm wondering.
Right now, we have a fairly predictable schedule that holds for most B1G teams, at least (with minor variation among schools):
8 conf
1 non-conf I-AA
2 non-conf non-BCS I-A (usually MAC, but also Sun Belt, WAC, etc.)
1 non-conf BCS
If we move up to 9 conference games, which non-conference game are the coaches going to drop? I'd think eventually we'll settle on a norm which will either be 1 I-AA and 2 non-BCS or going to 1 I-AA, 1 non-BCS and 1 BCS. But it will probably take 5-10 years for the expectation to become the new norm, and I'm just wondering what it will be. I think some of the other BCS schools have 9 game conference schedules, what do their teams do?
Please don't start arguing about how all the B1G teams have different schedules - sometimes they play 2 BCS schools a year, blah, blah, blah. I fully concede there is variation in scheduling, but I do think there is a fairly well-established expectation of the 1 I-AA, 2 non-BCS, 1 BCS non-conference slate.
