"Hughes' model" was designed with staff and put in working order before Hughes got bounced by compliance. That model will remain in tact, as requested from the top. A DPP, Two ADPPs. Some full time staffers. A good force of support staff interns, some of which I am guessing will be "volunteers" to ensure they can get the labor hours the coaches are pushing. Each coach assigned a region in Texas and some have additional regions OOS, as well as their respective position groups nationally. They'll also each have a group of evaluators dedicated to helping them find and evaluate prospects at their position and region. It's sounds similar to what I've heard former Saban assistants speak of. I don't know which of Texas' coaches have which regions in or out of state. I do know that Glasscock was hired and fit into the system Hughes started, not hired to bring his own.
For background on Hughes, he spent 4 years as an intern under Saban's front office staff while he was a student at Alabama. He's done it their way, or close to it, ever since from a structural perspective. Sark had that while in TTown, I assume his desire to keep it is a top priority for him based on his quick hiring of one who knew the ins and outs of the model and then hiring a backup that could be slotted into it. Regardless of how true to form it compares to Alabama down the road, it has already been described as quite an upgrade.
