Betting on football, and all other sports, has exploded since the Internet has invaded every home and cell phone on the planet. People no longer have to travel to a place like Las Vegas to visit a sportsbook, or go to a bookie who will break your legs. They can simply make a bet at one of a hundred gambling sites and wait for their cash to roll in, or, more likely, roll out.

The Niners and the Ravens are almost statistically identical in every way. Offensively, the Ravens barely beat the Niners by averaging 24.9 points per game to the Niners' 24.8. Both teams are also -0.6 in turnover margin. The only difference is on defense. The Niners only allow 17.1 points per game while the Ravens allow 21.5.

The Ravens will be looking to send their future hall of fame linebacker, and the soul of their team, Ray Lewis, out in style, as he has already announced his retirement. The Niners, on the other hand, are looking to begin a new era of San Francisco football with Colin Kaepernick, and their looking to begin that era with Lombardi Trophy.

Betting lines are thought up by some of the smartest minds in sports. While they're sometimes wrong, when they predict a spread to be somewhere around three points, it usually means the game is going to be pretty close. This is good for us because four of the last five Super Bowls have been decided by a touchdown or less and we've been spoiled. Nobody wants to watch a blowout (except for the fans of the winning team). Sunday's Super Bowl has the makings of a great game.
