I don't think KK was the problem. I think Tech just needs to be in the AAC or Mountain West conference. It doesn't really belong in a power 5. If they had a Boone Pickens type donor that would put insane amounts of money into the program, then maybe, they could be like Okie Lite (Which I consider a successful program).
I disagree because from what I understand they've upgraded their facilities. They have a decent sized stadium, and what impresses most is they have a solid fanbase. They usually sell out and their fans travel well for bowl games. They brought 15 to 20 thousand fans to the Alamo Bowl one year. I really think they want to compete but they've never been able to find the right coach. This time they should go the opposite way and hire a coach who has no previous ties as a coach or player. Brent Venables comes to mind. From what I've understood he's bought a home in Clemson, SC but if they make him an offer he can't refuse maybe he'll come.
