BB, Callahan coached since the 2004 season. We played OU in 2004 and 2005 regular seasons. If the cycle hasn't become obvious to you yet, each BIG 12 team from the North will play each team from the South, two years on and two years off. Hope that helps...
He might have been referring to Stoops with that, I'm not sure. Bring back punctuation in my opinion...
