I got a lot of questions about what head coach John Harbaugh meant when he blamed himself for some of the criticism that run game coordinator Juan Castillo has gotten, and attributed some of it to Castillo's title of run game coordinator. When the run game sunk to unthinkable levels, it was only natural to point the finger at the newly-appointed "run game" coordinator. However, I'm not sure if the criticism would have lessened if Castillo's title was offensive line coach, which is essentially the role that he occupied. Harbaugh gave that title to Castillo because it was a way to bring in another talented and highly thought of coach while not stripping the incumbent offensive line coach Andy Moeller of his title after Moeller's group performed so well during the playoffs. It was apparent from the first day of training camp that Moeller's role had diminished and Castillo had taken the coaching lead. Both men, along with assistant offensive line coach Todd Washington, handled the situation as best as they could. But as it turned out, the structure never worked. To put it in simple terms, there were just too many cooks in the kitchen, and that made things difficult. With Harbaugh announcing Castillo will be back with the title of offensive line coach, it seems inevitable that Moeller will be elsewhere.
