Though the Ducks have a sizable lead over the Sooners in the BCS now, that could change because of Oregon's weak schedule and OU's potential showdown with No. 3 Kansas looming in the Big 12 championship.
With a win over Kansas, could OU leapfrog Oregon in the BCS?
"That's the big question,” Billingsley said. "I think it's going to be so close.”
Where the Sooners can help themselves is in the Harris and coaches polls, which constitute two-thirds of the BCS standings.
At the moment, Oregon is No. 2 in both polls. OU is No. 3.
But what matters in those polls concerning the BCS are point values, not rankings.
The Ducks have 2,651 points in the Harris and 1,407 in the coaches.
The Sooners aren't far behind with 2,580 points in the Harris and 1,366 in the coaches.
If OU can register some style points with the voters over the next two weeks, those gaps could narrow heading into the Big 12 championship.
And a quality victory over the Jayhawks might be enough to put the Sooners ahead of the Ducks in both the Harris and Coaches polls.
And ultimately the BCS standings.
