Denbrock has been successful compared to the last two OC's
2022: Tommy Rees showed how he was basically trying to be Brian Kelly without Brian Kelly's decades of experience. The fact that he was the one who told Coach Freeman not to get a transfer portal QB, is what cost us at least 3 games that year.
2023: Gerad Parker was trying his best to call plays like Tommy Rees did. Sam Hartman often audibled out and helped cover up a lot of flaws.
Yes, Denbrock makes some mistakes.
That was painfully obvious in 2024 during the NIU game, as well as not calling plays that could have exploited the one soft spot in tOSU's defense (secondary) during the national championship game.
Or, in 2025, when he tried to play not to lose against Miami, calling too much dink 'n dunk.
However, we don't get to where we are now, if we had stuck with the Brian Kelly wannabes.
