I agree with your sentiment, but not the logic in that it changes anything if it is today or in 12 days he is fired.
You mentioned an employee who is underperforming, good example. But in what other job are candidates only available during a certain period? Makes sense to wait until they are available. You can be putting feelers out sure, which I bet they have to Frost.
All I am saying is relax. All a firing today would do is make you feel better, its not going to change Nebraska football one iota for the future.
