The last team to repeat as Super Bowl champions were the 2003-2004 New England Patriots. Their streak ended during the 2005 playoffs when they lost to the Denver Broncos. It's extremely hard to repeat as champs, according to The Baltimore Sun.

"When you win a Super Bowl one year, the same effort and same preparation that you had that year is just not good enough to win a Super Bowl the next year," remarked ex-Ravens linebacker Peter Boulware.

Boulware was on the Ravens' 2000 championship squad. They stifled the New York Giants by a score of 34-7 in the 2001 Super Bowl. He went on to say that talent alone doesn't help you repeat.

"You just have to do everything better. To win a Super Bowl, so many things have to go right. So winning back-to-back means you're extremely good and you got the breaks all year, too."

So yes, a combination of luck, grit and determination is the key teams need to win a second title in a row. Even reaching another title game after winning the year before is an accomplishment. Brett Favre led the Packers to two straight Super Bowl appearances and one win. Other teams to reach multiple title games in a row include the 1970s Pittsburgh Steelers and the 1990sDenver Broncos.

"I've learned this: You truly find out a lot about yourself after you've won your first," said Tedy Bruschi, an ex-Patriots linebacker and current TV analyst. "To still have the motivation to win another one next year, that really takes a special team."

Even the coaching staff needs to prepare better and better.

"Coaches can't get complacent, the general manager can't, the scouts can't," said Scott Pioli, a Patriots and Kansas City Chiefs executive. "People always insinuate that it's just the players that you have to worry about, and it's not. As leaders, [coach Bill Belichick] and I certainly worried about ourselves, too. It becomes an institutional rally that you have to keep an entire organization stimulated and aware of the potential pitfalls."

Do you think the winner of Super Bowl 48 in the Meadowlands will repeat as champs the next season?
