This is probably my biggest problem with Sark. His job is to be the HEAD COACH of the University of Texas and be responsible for ALL aspects of the team. During a game he should be thinking about O, D, and ST, not focusing on which play he should be starting the next offensive series with. I don’t know that bringing in another DC, no matter how good, solves that fundamental issue
If Sark is really ALL IN for ‘26 he needs to do himself and the team a favor and get an OC / Play Caller that he can work with and shift his focus to being the best Head Coach that he can be. That doesn’t mean he can’t have input on play design and play calling, it just transfers the primary responsibility of that to someone else so that he can manage the game as a whole.
