Jim Harbaugh watched Friday's A's game in the most Jim Harbaugh way possible

49ers head coach Jim Harbaugh is an intense man. He's intense when a challenge call goes against him, and he's intense when pounding his glove at an Athletics game, waiting for a foul to come his way.

Go ahead, A's players. I dare you not to hit one to him.

In the same game, we caught up with a decidedly happier-looking Harbaugh, who talked about his Little League days, Colin Kaepernick's first pitch at AT&T Park and his support for all Bay Area teams:
