There are multiple ways for us to make it, if you assume that ACC, Big12, and Group of 5 get 1 each, and that is a fair assumption. Any one of these could put us in. I am forgetting about true longshot possibilities like Penn St losing at home to Maryland
1) The committee values Tennessee's resume over Ole Miss's right now, so that if we win out we'd be in almost no matter what. This is a real possibility because our best win (Bama vs Georgia) is equal to their best win, and our losses (Ga vs LSU, Ark vs Ky) are better also. (can't quantify what human opinions are)
2) Penn State loses to Minnesota Saturday (~20%)
3) Notre Dame loses to either Army or USC (~35%)
4) Ole Miss loses to Florida Saturday (20%)
5) Indiana gets a mudhole stomped in them Saturday by 25+, which is what I think it would take to drop them below us (15%)
6) Ohio State loses to Indiana and the committee values our resume over theirs...hard to quantify the likelihood of that but Oh St losing is 20%
7) Alabama loses at Oklahoma (10%)
8) Georgia loses to GaTech (5-10%)
9) Texas loses to TxA&M and the committee values our resume over theirs
All of those things above not happening is way less likely than any one of them happening...and of course we'd need to win out
