Hypothetical: If we're 2-4 and lose to Denver on national TV, is DA fired?
Anyone who thinks this is even a possibility hasn’t been paying much attention to the last few years. Mickey Loomis isn’t ever going to fire a HC mid season.
If we miss the playoffs then I expect Allen will be fired. That would be 3 years of no playoffs having changed the QB and coaching staff multiple times. There would only be the HC left to change.
