7-1 is only 8 games so it doesn't count the CCG.
Correct. They are assuming 1 conference loss, and a loss in the Big 12 CCG to OU.
So they're saying Nebraska loses to Texas, Oklahoma loses to Texas, and Texas gets upset by aTm and Mizzou?
They don't list specific wins and losses, just a record for each team. From my reading, I'm guessing they have us losing to aTm during the regular season, and Texas losing to us and OU. OU's loss is probably a Stoops special to aTm or Missouri...
