As the head coach, Harbaugh is stuck in the middle. He isn't in the front office, so he doesn't handle contracts. He isn't a player, so he has to stay neutral. Regardless of whether Gaither or Reed plays this year, Harbaugh has to have them ready to play if they do return. If he says something negative about them or sides with ownership about them not getting a new contract, they might get mad and stay out longer. If he sides with the players, I'm sure he would be getting a call from the owner or a visit from across the hall from general manager Ozzie Newsome.
