The administration has changed both Presidents and Athletic Directors in the past ten years. So the current ones are not a common factor with the problems of the late Brown era, or the entire Strong era.
This "Austin is soft" theme, that I've seen since about 1995, is an excuse by apologists of bad coaches, to claim that while they are failing, it's not their fault, too many things to do in Austin. I've even seen 6th Street, back when it wasn't bum and hoodlum infested dump, blamed, as if other college towns don't have bars too.
As for the foolish article:
Mack is a great coach. Not a good coach, a great coach. Merely good coaches don't win national titles, given how steep that mountain is.
Lots of coaches that would not be considered great coaches have won NC - Phil Fulmer being one, Larry Coker from Miami 2001, coach at Auburn with Cam, even Jumbo Fisher won a title. Brown was a good coach overall, who started good (98-99), was outclassed by Stoops from 2000-2004, ran a great program from 2005-2009, then got foolish and tried to totally change the offensive philosophy in 2010 to a power run (?) game, from having been beaten by Alabama in the NC game. Sort of a Stockholm Syndrome there. Then from 2010 to 2013, a tired, lazy coach, who was coasting, burned out, and needed to retire but was too stubborn to admit he has lost what it took.
Mack was said to have lost it, yet here he is leading a top-tier program again at Carolina.
Now he's back at NC, doing well there, as such - he won't win any more games than he did during his coasting years at Texas but NC is fine with 8-4 seasons and it's a good fit for him - it's like a PGA player who goes to the Senior tour and starts winning, after years of not making the Saturday cut. Doesn't mean he's ready for the Masters again.
Charlie Strong has succeeded everywhere he's been.
Now this is just a lie. Dude was fired after three seasons at USF, each one being worse than the last (sound familar)? His era at Texas was the worst stretch of Texas football in history. He had 2 good years at Louisville, in a weak Big East Conference. He's not a good coach.
Except Austin. Tom Herman has succeeded everywhere he's been. Except Austin. Hell, he won a major bowl and spanked FSU and OU in consecutive games at Houston.
Herman's only other head coach job was at Houston. He had two decent seasons there, and a few good wins. They beat FSU in a bowl game one year, then OU the next season. Then went 5-3 in the AAC, hardly a powerhouse conference, and finished 3rd. I think Saban's place in college football history is safe.
The rest of the article isn't worth reading, due to the flaw of its basic premise - that Texas is a death valley where coaches wither and die.
