Consider the source (link to the Daily Oklahoman), but it's an interesting read nonetheless.
A Texas source said over the weekend that UT might encourage Mack Brown to retire, that the ‘Horns might be ready to commence with the Muschamp era. Not because of any dissatisfaction of Brown, but because of a belief in Muschamp. That’s the extent of Texas’ devotion to Muschamp, who is in his third year as the UT defensive coordinator and has been designated Brown’s successor.
