I don't really think that Stoops has gotten stale, per say. I think that what we are seeing at OU, and really at Texas, over the last few years is the emergence of other programs in Texas. For years, talent in Texas either landed in Austin or Norman. Now, we see programs like TCU, Baylor, Tech, OSU and others getting talent that in past year they never really got. That impacts OU. The other thing I think we are seeing is the reliance Stoops' program has on quality QBs. Landry is OK but he is not superior with regards to OU's hurry up offensive approach. He is simply not as well suited to that style of offense as have been some of his predecessors. Texas is struggling with the same issue in that they missed on Gilbert. However, they are not as tied to QB success as is Stoops. I have believed for a very long time that if you could stop OU on first down, you could beat them consistently. It's because once that hurry up gets rolling, it limits your ability to change personnel groupings and it wears down your defense. If you stop them, you can beat them because then you have all options open to you on defense. It also means you are probably having success on offense because your seeing more opportunities to score.
Just my opinion.
