SANTA CLARA, Calif. — Jim Harbaugh pirouetted in frustration following a personal foul on Dan Skuta. He got hit with his own unsportsmanlike conduct penalty for arguing following a catch by Vernon Davis that went to review before being ruled a touchdown.And that was just last Sunday.Harbaugh has been at his emotional best — or, to some, worst — with his cartoon-like faces and quirky sideline antics in leading San Francisco back to the NFC championship game for the third time in as many years since taking over as 49ers head coach in January 2011. On Davis’ TD during Sunday’s 23-10 win at Carolina, Harbaugh ran well onto the field during the play.“I think Harbaugh gets away with murder myself,” former Seahawks coach and ex-49ers assistant Mike Holmgren said.
