Wanted to mention that Sark did not "start cleaning house with creative" and did not let Lange or Turnquist go. First, creative department doesn't report to Sark, they report to DPP.
Second, both guys are very ambitious and talented individuals. While they both love sports, this part of the creative industry does not leave much room for career growth after you get to where they're at. Working directly for a team is typically much longer hours, much larger volume of work, and more work to oversee than other jobs outside of a sports program at their level. Matt didn't enjoy doing some aspects of his role that are necessary, but he was viewed very favorably in the department anyway. If they wanted to stay, they could have. They're both moving on to jobs that will allow them to have more time with their families, less volume, and more income.
Sark and Billy view their roles as an important part of the program and recruiting. so I have faith they will hire people who are hungry like Lange and Turnquist were and not hire just anybody. As of right now I'm not sure if their replacements are lined up or if that's something they'll wait until Spring or later for.
Moving on, I am excited to see what the recruiting trio of Banks, Choice, and Gilbert will be like. It can't be undersold how excellent a hire Gilbert was by Sark, he has been an absolute force for Texas this season. I am hoping Choice brings Texas an opportunity to build on that.
