Looking at the schedules of the teams in front of us, it seems pretty clear to me that if we win 10 we're in.
Likely in:
OSU
Miami
Oregon
Ole Miss
If true, that means (i) Penn State is on a bubble (with likely losses to OSU, Oregon and maybe Indiana...). Also, with 6 ranked teams in front of them, OK will almost certainly end with 3 or more losses. Texas A&M vs LSU will be for 1 spot, and Indiana is probably in.
So, if you're scoring at home, that's 6 in and 3 out. Assume Texas loses to 2 of 3 to Texas A&M, Georgia, and Oklahoma, and we're 4 out. Assume Alabama makes it in, and Tennessee is out. So, that's 7 in, 5 out. If Texas Tech is in for the Big12, then Iowa State is out; 8 in, 6 out. If Georgia is in, then Ga Tech is likely out; 9 in, 7 out. Vandy ends with 3, likely 4 losses, so 9 in, 8 out. Missouri is a tough call; let's call it pro-SEC bias, and we're 10 in, 8 out.
We need USC to be Michigan; if so and we beat USC, we're ahead of Michigan, and Michigan is out. Even if that doesn't work, we likely end up team #12. Assuming any amount of chaos, we're even better off. So win and we're in.
What am I missing?
