The Sooners also may not be able to fend off the victor of this weekend's LSU at Auburn showdown — if that team runs the table.
"OU's position is not as good as it looks," said Brad Edwards, ESPN's BCS guru. "If LSU or Auburn goes undefeated, the first team they will jump is Oklahoma."
The good news for the Sooners is that the probability of Oregon and Auburn or LSU going undefeated is slim.
All six of Oregon's remaining opponents are .500 or better, and the Ducks have a trio of daunting road games at USC, Cal and Oregon State.
Even if it beats Auburn, LSU still has to run the gauntlet of Alabama at home and Arkansas on the road, plus the SEC Championship game.
Auburn still has to travel to Alabama.
More good news for the Sooners is they don't have to worry about competing with the Big Ten champ. With Ohio State losing to Wisconsin, the Big Ten's lone undefeated team is Michigan State, ranked No. 7 in the BCS.
Palm doesn't believe the Spartans can't catch an undefeated OU in the BCS; nor can Boise State or TCU.
"They don't have to worry about those teams," Palm said. "Just Oregon and an undefeated SEC team."
