The 49ers opened as 5-point favorites, but that has shrunk a little bit over the last week and a half. Unless something drastic happens, the 49ers will be the favorites heading into Sunday night's game.
Despite the 49ers being the favorites since day one, the teams are close in a lot of respects. The Ravens averaged 24.9 points per game this season, while the 49ers were at 24.8. They also had an identical turnover differential at -0.6.
The biggest story line, of course, is the Harbaugh brothers coaching against each other. But the main highlight Sunday, when it comes to things actually on the field, is the young, fast Colin Kaepernick against the old, tested Ravens defense. The Ravens defense has held up all this way and survived Tom Brady and Peyton Manning, but can it stop Kaepernick?
