San Francisco 49ers head coach Jim Harbaugh is known to wear his emotions on his sleeve, and that apparently includes events where he is only a spectator. Harbaugh attended Friday night's Oakland A's game at the O.co Coliseum. Not only did he come prepared with a glove in case a foul ball came his way, but he brought the intense look on his face that we're normally accustomed to seeing while he coaches the Niners on the sidelines. Interestingly enough, Harbaugh seemed much happier when attending a taping of Judge Judy with his father earlier this month. Must be mentally preparing himself for the upcoming season. H/T FTW.
