There is no Steinbrenner-Martin dynamic anymore. Managers dont get fired after 1 year unless there is something really bad that happens. So no youre not going to have a manager every year.
Its hilarious though how some people feel the manager doesnt have to be accountable for anything. The FO is the one controlling all the aspects of the job. Or its always the injuries. Or its always the players. Must be nice to be paid so much money to be completely along for the ride.
You're literally describing your attitude toward Harbaugh after 17 seasons. Hyde's in his 3rd season with an actual MLB caliber team.
