Texas fans may consider this some kind of sacrilege, but Mack Brown appears to have outlived his usefulness as head coach.

With Ohio State's Jim Tressel out of the picture, no coach grasps his single national title harder. Plus, Brown's teams have been mediocre by Texas standards in recent seasons. Losing 63-21 to Oklahoma on Saturday in the Red River Rivalry does not help him much.

Should a coach at Texas who can't beat Oklahoma remain the Longhorns' coach?

Brown is now 5-9 against the Sooners, with his team losing three straight to Bob Stoops' squad.

If it is time for Brown to go, who might replace him?

Here are the top candidates.
