First, do you remember Texas football pre-Mack Brown? If not well then you should do some research. Has Mack Brown underachieved? Possibly, but he does have two conference titles, a national title, and a Heisman trophy recipient during his tenure. Now I understand and agree that with the talent Texas has and with the consistent top recruiting classes that their performance is unacceptable. However, Mack has stated time and time that he is a CEO coach and allows his coordinators to coach. It may not be the most popular or effective method but it has proven to be successful.
I'm not saying Mack should be fired or forced out. However, if UT seeks a new coach I would be excited about a new era and the possibilities of the potential coaches out there. I would also be excited if Mack admitted he made mistakes by hiring Diaz, Harsin, and Applewhite (there should be no such thing as co-coordinators). Removing these individuals and replacing them with more competent and experienced coaches would be just as exciting. The offense seems too "gimmicky" (UT needs to get back to north and south with a dominant line and less side to side action) and the defense, well that's just an obvious problem.
Calling Mack Brown greedy and out of touch with reality is quite embarrassing and disgraceful as a fellow longhorn. He has done great things for the program and was in the national title game just a few years ago. I doubt he has just lost it all of a sudden. Furthermore, why would UT want Applewhite as a head coach? He doesn't have the experience and is not even trusted to coach the entire offense (only rb's). I loved Applewhite as a player and I hope he excels as a coach in the future, but replacing Mack Brown with him is one of the most ridiculous statements I have heard. From rb's coach to head coach?
The problem at UT is not a complex problem. The balance of power in football is always swinging. Yes a&m (shockingly I will admit) has had a great year. While the win over Bama was beyond impressive remember they lost to the other good SEC teams in their conference (FL and LSU) and to assume they will maintain this status is a bit premature. UT can and will maintain a top recruiting class. At this point the remedy is better coordinators who can develop the talent. If Mack Brown steps down or is unfortunately fired then I wish him the best. He deserves nothing but respect and admiration from the UT fan base. Things haven't been perfect and right now they are pretty painful, but that doesn't erase the positives of his time in Austin.
