If next year plays out like this year did, with A&M killing it and Texas and OU not doing anything exciting by their standards, I think they should worry a bit.
That's just a bad trend. Texas has been king of the state for so long, and OU was always able to take some of the tier 1 talent Texas didn't take, they seemed to have a pretty good system going. A&M being the cool school in Texas just throws everything out of balance. Plus, Mack's probably just hanging on at this point, and Stoops might be getting stale in Norman--they're not really in shape to challenge A&M's rise. And KSU and Okie State can't be expected to carry the conference's water every year, they're still programs that need to rebuild occasionally. The conference goes where UT & OU go, and those programs don't look to be trending upward right now.
