By firing Wells now, they are also getting a head start on other coaching candidates. There is some uncertainty now surrounding the Big 12 with the UT/OU defection, TV deal uncertainty, etc., so the conference is a harder sell. TT can get their sales pitch in a few ears now, ahead of the noise of the coaching change free-for-all at season's end.
Had a family member who was part of the Athletic Department at one of Wells’s previous schools and said the guy is a complete a-hole.
