This is Jim Harbaugh's best chance to humanize himself, show another dimension beyond the coaching brilliance and animated sideline temper.
Maybe tell a quick, amusing story about growing up with his older brother, John. Or marvel at the improbability of sharing the biggest stage in sports alongside the same guy with whom he once shared a room.
Harbaugh arrived at his weekly news conference Monday in vintage form: black sweatshirt, tan pants, guarded tone. It's the formula he used all season in guiding the 49ers into the Super Bowl, so he clearly sees no need to shift gears now.
