08:15 AM ET 01.31 | As the brothers Stoops look to the future, they are more likely than ever to do so with an eye on the power of three, as in the 3-4. Chatting with OU commit Jordan Evans last Saturday, I learned that the Sooner staff is telling recruits that OU likely will change to a 3-4 defense. It only made sense and we figured that would be the case, but now we have confirmation that the coaches are seriously looking at it. And it's clear why. Lack of defensive tackles. The Sooners hope a 3-4 leads to a better pass rush, but the move to a 3-4 is out of necessity. OU was wiped out at defensive tackle -- Jamarkus McFarland, David King, Casey Walker and Stacey McGee, all gone.
