Hypothetical: If we're 2-4 and lose to Denver on national TV, is DA fired?

Nope, Mickey Loomis keeps people for years longer than he should just for the sake of doing it. Unless we finish the season 4-13 or something like that nothing will change. Carr will continue to be our underwhelming QB and DA will still be here to make sure the defense collapses at the end of any close game.
