Thanksgiving  is a day for appreciating what you have while we all sit across the  dinner table from each other. Thursday night in Baltimore, a pair of  family members will spend the evening across the field from each other.
For the first time in NFL history, brothers turned head coaches will face off as Jim Harbaugh’s 49ers visit John Harbaugh’s  Ravens. Making the matchup even more enticing is the fact that the  Niners sport the league’s second-best record at 9-1 and are coasting in  the NFC West (where the other three teams are a combined 9-21), while  Baltimore is tied with the Steelers for the lead in the AFC North.
And could this be the first of two meetings between the brothers this season?
