For all of you chess enthusiasts. Butch Jones and Jon Gruden (or any other coach for that matter) are not connected and not a package deal. So, firing Butch and naming an interim does not affect your ability to select his replacement.
As Doc so eloquently stated, I do not see any benefit to Butch coaching another practice, let alone game. The Universitys exposure is capped by the buyout provision in the contract. The University could try to press to get the amount to zero, but that could take years to resolve. Or, it could use its leverage to negotiate something in between.
Waiting provides no benefit. If anything, it can be argued that it is a ratification of Butchs misdeeds and cant be used down the line.
In my experience, indecisiveness has never led to a good result. Decisive action does.
