Two of the biggest story lines for Super Bowl 47 in New Orleans are the coaching matchup between the Brothers Harbaugh and the last game of longtime Baltimore Ravens Linebacker Ray Lewis.

John Harbaugh is the head coach of the Baltimore Ravens and older brother of San Fransisco 49ers Head Coach Jim Harbaugh.

This is the first Super Bowl matchup which will pit brother head coaches against each other and the second time that Jim and John will face off against one another. John won the first meeting last season in Baltimore 16-6.

The other story line for the game is the retirement of Linebacker Ray Lewis for the Ravens. Lewis missed half the season due to an arm injury and didn't return until the first round of the AFC Playoffs.

Which is the bigger story line? Ray Lewis retiring or the Harbaugh Brothers facing each other in New Orleans?
