The San Francisco 49ers are currently the odds-on favorite to win Super Bowl XLVII, according to oddsshark.com. Recent money on the Baltimore Ravens has reduced the spread, however. The Niners are now favored by 3.5 points after opening as five-point favorites last Sunday.

The over/under has shifted down as well. After opening at 50 points, most sports books are now setting the combined score between the two teams at 47.5 points. The scoring average for both teams on the season would surpass that--the Ravens average 24.9 points per game, and the 49ers average 24.8--but both teams also have better-than-average defenses.
The SB Nation 49ers blog Niners Nation also has a look at some of the early prop bets available, including odds on who will score the first touchdown (Frank Gore favored at 13/2), who will win MVP (Colin Kaepernick favored at 7/4), and whether the coin toss will come up head or tails (no odds, obviously).
