1. DANCE, DANCE, DANCE

Ravens fans will rock the building during Ray Lewis’ pregame Squirrel Dance, a YouTube sensation that Lewis surely will perform for the final time before retiring. Will smoke and flames accompany the star linebacker’s ritual?

2. TATTOO U

Count the tattoos, from the Ravens’ Ray Lewis to 49ers QB Colin Kaepernick to, well, just about everyone on the field. Try to count how many players don’t have tattoos.

3. TAKE THAT!

This Super Bowl features some of the hardest-hitting defenders in the league. Both defenses are exceptionally physical, with Baltimore led by Ray Lewis, safety Bernard Pollard and end Paul Kruger, while San Francisco features linebackers Patrick Willis and NaVorro Bowman, lineman Justin Smith and safety Donte Whitner.

4. SUPER PERFECTION

With a win, the 49ers would match the Pittsburgh Steelers with six Super Bowl crowns. The Steelers, though, have lost twice in the big game. The 49ers are 5-0 in championship games.

5. HAND JIVE

Keep your eyes on the traditional postgame handshake between the coaching Harbaugh brothers, John of the Ravens and younger brother Jim of the 49ers. Jim, by the way, is known for his extra hard handshake followed by a hard backslap (ask Lions coach Jim Schwartz). For that matter, keep an eye on their interaction before the game.
