I have to keep going back to the way the Mack era ended.
For all the good Mack did (and it was a ton of good), he and his staff ran out of gas several seasons before he left. Colt's brilliance papered over a lot, but the work ethic both from the coaches and consequently the players dropped several notches. I believe that, when TPTB nudged Mack out the door, they really though Nick Saban was on his way over. Not only was that not happening, but DeLoss Dodd rode off as well. For as annoying as the big boss can be, he really presided over the transformation of the Texas Athletic Department from a department at a University into a global brand.
I'm not sure how Steve Patterson ended up as the AD, but this was a pivotally poor decision. His specialty is cheap. He can theoretically help a cash strapped pro team survive lean years. This is NOT the Texas Athletics Department. You pay for experience, and Steve wasn't paying for anything. I'm a believer in Charlie Strong, and believe he was getting educated in how to be a head coach. His pedigree was defense, he didn't know offense, and Texas was buying him an education by losing football games.
I don't believe Herman was ever going to learn because he thought Urban Meyer taught him all he'd ever need to know. Like a poor dog trainer, he thought that if he just beat the animal harder, eventually it'd do things the right way. Kids already mad at losing Charlie Strong weren't playing that game.
After we lost Colt, Mack thought we should have Alabama's offense. Strong took it and thought we should have no offense. Herman wanted tOSU's offense.
I believe Texas has the perfect staff for its mission right now. I think what we saw last Saturday was largely on-field panic when things weren't working. Card was indecisive as only a 19 year old making his second start on the road against a historic rival could be. When things got ugly, the OL abandoned their drilling and reverted to 4 years of muscle memory - which was regrettably poor form and no real direction. They lack a field sergeant to grab their facemask and re-focus everyone's brain. One must emerge if Texas is to escape similar situations (and they'll come up).
No substitute for experience. Texas has good players and a fantastic staff. For the first time in a decade, everyone is pulling the same direction. You can't skip steps though.
