BCS Battle
The Texas-Oklahoma game matters to USC because the Longhorns and Sooners are both in the top five and it has BCS ramifications. Here's what happened in past meetings when both teams were in the top five:
1950 No. 3 Oklahoma def. No. 4 Texas 14-13
1963 No. 2 Texas def. No. 1 Oklahoma 28-7
1975 No. 2 Oklahoma def. No. 5 Texas 24-17
1977 No. 2 Oklahoma def. No. 5 Texas 13-6
1979 No. 4 Texas def. No. 3 Oklahoma 16-7
1984 No. 1 Texas tied No. 3 Oklahoma 15-15
2001 No. 3 Oklahoma def. No. 5 Texas 14-3
2002 No. 2 Oklahoma def. No. 3 Texas 35-24
2004 No. 2 Oklahoma def. No. 5 Texas 12-0
Looking at Oklahoma and Texas' schedules, in terms of bettering USCs position/BCS Ranking and shot at the National Championship, I think a Texas win is better.
Texas has a more difficult schedule (they play #2 Missourri the next week), thus their chances of losing another game are higher.
that being said, Oklahoma looks like a better team at this point.
Well, then wouldn't you want Texas to lose? If they are more likely to lose down the line, then a loss Saturday would put them out of the BCS picture. Because if Texas wins, and then loses to No. 2 Missouri and Oklahoma only loses to Texas, both would more than likely finish ahead of USC, because their losses would be to highly-ranked teams, sted of a team (Oregon State) that will likely finish below .500. From a BCS ratings stand point if would seem that USC, because of the loss to Oregon State, would be at the end of a line of all the possible one-loss teams.
Scenario:
If Texas Beats Oklahoma. Oklahoma drops, Texas Rises.
If Florida beats LSU. LSU Drops, Florida Rises
As long as SC takes care of business, they continue to rise. So in essence, after this weekend, SC could theoretically be ranked #6/#7 (if they lose, of course, the NCG is very unlikely)
Texas and Missouri play next week, one will lose. LSU and Alabama still must play too, one will lose. Missouri will most likely play in the Big 12 Championship game against the winner of OU/UT game, one will lose.
So
#1 Oklahoma must play Texas and Missouri*
#2 Missouri must play Texas and Oklahoma*
#3 LSU must play Florida and Alabama and Georgia/Florida/Vandy*
#4 Alabama still must play LSU and Georgia/Florida/Vandy*
#5 Texas must play Oklahoma and Missouri and Missouri*
#6 Penn State still must play OSU with Prior and Wells in the shoe.
#7 Texas Tech still must play the whole Big 12
#8 BYU will drop below SC on strength of schedule, even if they beat UTAH and TCU
Basically, since many of the teams ahead of SC must play each other, USC still controls its own destiny IF they can continue to dominate on the field as they have in the three victories.
