NEW ORLEANS -- Jack and Jackie Harbaugh said they are as neutral as they can get when it comes to Sunday's Super Bowl, which will feature their sons.

Family members and friends are making the trek to New Orleans to witness an NFL first as John Harbaugh leads the Ravens and Jim Harbaugh leads the San Francisco 49ers in Super Bowl XLVII.

On Wednesday, Jack and Jackie Harbaugh repeated how proud they are of their sons in a 40-minute news conference at the New Orleans Convention Center.

"I honestly have to say that the birth of our own children and then the birth of our grandchildren are the most important to me, and this is like frosting on the cake for our whole family, our extended family, which includes a lot of relatives and our extended football families at all the universities where we have been and Jack has coached football teams," Jackie Harbaugh said.

When the brothers faced each other on Thanksgiving Day in 2011, the Ravens won 16-6 and gave the family a feel for what this weekend might be like. Jack Harbaugh said there aren't any emotions when the teams are playing and the hardest part comes when the game is over.

"The one thing that I think about is after the game there is going to be one winner and there is going to be one that's going to be totally disappointed and my thoughts go to that one that will not experience the thrill of victory," Jack Harbaugh said. "... Every parent can identify with the thrill of victory and the agony of defeat and Sunday night we're going to experience both of those great emotions and our thoughts will be with the one who comes up a little short."

But the Harbaughs are embracing the experience.

"One thing that both of them have shared with us, 'Mom and Dad, please promise us that you will enjoy this, enjoy this experience. That's all we're asking. Please, please enjoy this experience.' And we're trying, I promise you we're trying," Jack Harbaugh said.

Added Jackie Harbaugh: "And they're telling their teams the same thing. Enjoy this moment. And they're going to take it all in, as they should."
