Few thoughts.
1. To date the best team blOwU has faced is UCLA, think about that for a moment. This is not battle tested group. On Saturday, Texas will be by far the most talented team they will face all year. So far their defense hasn't faced a good offense. ISU has the 127 ranked offense, UCLA has 107, and Baylor has the 26th ranked offense, but when look at their schedule you have to ask why is it so low.
The best defense they faced was ISU and again when you see who ISU has played so far you have to ask why is it ranked so low.
2. Oklahoma's defense is ranked 20th but isn't necessarily the best defense Texas will face. TCU who has played Texas and Ohio State actually is better defensively. The Texas offense should be able to both move the ball and score on this team. It will be disappointing if Texas can't score more than 30 pts against them.
3. Oklahoma's vs. the Texas defense. This is where the rubber meets the road. Can Texas stop Kyler Murray? It's no secret that Texas has trouble stopping athletic QBs. Again, what I look at is matchups and when matching up the Oklahoma receivers to the Texas DBs it comes down to the fact that the Texas DBs have faced a TCU passing attack with faster more dangerous receivers. They are without their best RB an advantage to Texas as he is really good. When I look statistically at the defenses they have faced, it's a combination of good offense crushing bad defenses. Texas again will be the best defense they face until TCU.
I like our chances in this game. We are not a 13 pt dog to them, if anything Texas should be favored. The game was close last year and that was with a better offense and defense than they have this year. Don't be fooled by their ranking and being undefeated, they have done nothing to deserve that ranking.
