Although not an expert, I do believe Texas schemed and performed very well in the first half against the sooners. They failed to adapt to the QB change and played a lot of prevent type defense which proved extremely costly. Kansas seemed prepared to stop the run and make Williams beat them. In the end, they did not have the talent to sustain it for 4 quarters. I missed a lot of the OSU game and have not had the stomach to go back and watch it so I am not sure where all the breakdowns occurred.
Another issue with our defense in both games in my opinion is that we do not have an offense that can wear opponents down or dominate the time of possession for an entire game. Thinking about the teams that have had success slowing down OU, they have sustained drives and controlled the clock. Whether it is the OL, lack of development, coaching, or a combination of all of the above, the most successful defenses have complimentary offenses that control the game. We have not demonstrated that so far.
All of these issues lead me to believe the "close" comment by Sark is likely not the comment he is making behind closed doors to the defensive or offensive staffs. At least I hope it is not. Sorry for the lengthy post, bored without a Longhorn game to watch....or cry about.
