Are the Bombers doomed again?

Essendon have named their new coach - James Hird. While I respect the bloke as a player and he is super knowledgeable about the game I do wonder why Bombers have appointed an inexperienced senior coach for the second consecutive time. Especially given Hird has had extremely limited coaching experience. There is talk of hiring a ex-senior coach for an assistants position (Bomber Thompson's name has been bandied around), but will that be enough to mentor the new coach to his role?
