Auburn will still be unanimous #1 in computers, so their BCS average will be 0.9611 - it actually goes up a bit because the total points/votes for Auburn in the two polls went up this week. If the average of the four computer polls that count for Oregon is 3.5 (i.e. 2 3's and 2 4's, or a 2, and 3 4's), then Auburn will be back in the #1 spot.
