NEW ORLEANS (AP) -- Colin Kaepernick is a mystery man under center, a strong-armed passer one moment and a 25-year-old kid who can run right out of the pocket for a huge gain the next.
Baltimore must brace for the unexpected on every snap in Sunday's Super Bowl.
There's flashy Michael Crabtree on the edges and Vernon Davis down the middle, Frank Gore and LaMichael James clogging things up in the running game.
The creative, switch-it-up San Francisco offense sure keeps opposing defenses guessing. The 49ers hope to do it again at the Superdome, when the Ravens will face an array of looks from Jim Harbaugh's team.
"With Kaepernick, it's like pick your poison," Hall of Fame receiver Jerry Rice said. "Are you going to try to shut down that pistol and not let him get outside, where you've got Frank Gore and LaMichael James going downhill? Then, Crabtree and Vernon Davis on the outside. I think the secondary of Baltimore, right there in the middle, is where they're going to get exposed. ... If you double team Crabtree, it's going to be Vernon Davis. If you get Crabtree one on one -- for some reason he's playing with a swagger right now that's unbelievable."
Kaepernick has shown two drastically different styles in two postseason games. What he'll show the Ravens is anybody's guess.
In a 45-31 rout of the Packers in the divisional round, Kaepernick ran for a quarterback playoff record 181 yards and two touchdowns and also threw for 263 yards with two TD passes to Michael Crabtree.
A week later at Atlanta, everything looked different in a 28-24 win that sent San Francisco to its first Super Bowl in 18 years.
Kaepernick only ran the ball twice, instead handing off to his go-to guy, Gore, and the Niners rallied from a 17-0 deficit for the biggest comeback in an NFC championship game.
"He's very good, he's very accurate," Ravens defensive coordinator Dean Pees said of Kaepernick. "They've done a great job with putting him into a system and building a system to make him successful, but to be able to throw the ball deep you have to have guys that can run deep. Crabtree and Vernon Davis and Randy Moss can run deep."
And Gore can grind out yards.
Gore, coming off his franchise-record sixth 1,000-yard rushing season, ran for second-half touchdowns of 5 and 9 yards in the comeback in his first career postseason performance with two TDs against the Falcons. He has three touchdowns and 209 yards rushing during this postseason run.
A balanced offense, indeed.
"There's a lot," Crabtree said. "I could go on talking about the talent that we have around here. On the tight ends, running backs, you have to remember we have three people injured that played a major part in our offense. But I would say that with all of these weapons, I don't think that you can go wrong."
After a quiet year in which he faced double-teams and constant attention by defenses, Davis broke out at Atlanta with five catches for 106 yards with a 4-yard TD grab.
"He does it all. He's a beast," Ravens safety Ed Reed said. "He's one of those guys that you all say has it. He catches touchdowns, he's blocking. I'm surprised they haven't ran him yet, handing him the ball, but he's somebody you really have to know where he is at all times and be mindful of what he's doing, because they give him the ball, for one. You have to give him the ball. Why wouldn't you? But whoever is covering him, whether it's me, (safety) Bernard (Pollard), or anybody on our team covering him, you have to be really mindful of where he's at."
Crabtree had six catches against the Falcons and Randy Moss -- who this week proclaimed himself "the greatest receiver ever to play this game" only to have Hall of Famer Jerry Rice beg to differ -- made three.
San Francisco's offensive line will have to do a better job than in a 16-6 loss at Baltimore on Thanksgiving night 2011, when the unit allowed the Ravens to match a franchise record with nine sacks.
"We've seen enough film to kind of know what to expect, unless they come up with something different," center Jonathan Goodwin said. "But definitely a talented group up front, and that's what makes them a good defense. They try to do some things to confuse you."
