Big screens, wings, drinks, and predictions. Whether right or wrong, bold picks have become a staple of Super Bowl Sunday much like the rest of the party fare.

Over the past eight years, the underdog has covered the spread. That should put Baltimore Ravens fans in a good mood, along with many experts picking them to outright defeat the San Francisco 49ers in New Orleans.

San Francisco is favored by four points, with second-year quarterback Colin Kaepernick leading the way. Ravens quarterback Joe Flacco and his stellar play this postseason were big reasons experts went against Vegas oddsmakers.

San Francisco’s Frank Gore and Baltimore's Ray Rice were also mentioned as "X factors," with both team’s success hinging on their ability to run the ball Sunday.

Check out some of the experts' predictions and scores below.

Never hesitant to give an opinion, Mike Florio said: “There’s something about the Ravens this year, between the impact of Ray Lewis and the emergence of Joe Flacco and the reality that, after this season, Baltimore could have some rebuilding to do. For the 49ers, they could be back on a much more regular basis. In the end, there’s a good chance that each Harbaugh brother will get a ring. For now, the first-born son becomes the first one to hoist the trophy.”
