Janie McCauley from AP just asked Jim Harbaugh if he is an innovative play caller.

Without hesitating, Harbaugh replied, “This is a Greg Roman offense.”

Interesting. Enlightening.

Harbaugh said Roman designs most of the play book and calls the plays.

Before the season started I asked Harbaugh who calls the plays and he got all quiet and secretive in the Harbaugh-secretive manner like the entire world is at stake depending on how he answers. Now we know Roman, who is terrific, is in charge of the offense. And we also know Harbaugh trusts his generals and gives them credit.
