especially against Auburn and UT.
If Auburn crashes and UT isn't good then we'll have a bunch of wins against mediocre or worse teams which will get us somewhere between 20-25. If we are dominating in our wins, we can probably move higher even if we don't have a great win.
If either Auburn or UT have a good record, I think we'll be closer to the 15-17 range.
Even if Auburn is not good though, we'll probably get a bigger boost than we should out of them b/c it will still look like a good win. Also, if most of the undefeated teams fall relatively early, we would get a boost just for being undefeated and in the SEC, even without a particularly good win.
