2013 Super Bowl: Safety Donte Whitner says 49ers 'still have work to do'

More than a week removed from their respective conference championship games, the Baltimore Ravens and San Francisco 49ers have had extra time to prep for their opponent in the ultimate showdown that Super Bowl XLVII provides.

But according to 49ers safety Donte Whitner, the extra time still hasn't pushed San Francisco to the point where they're ready to take on the Ravens. He says the 49ers still have some wrinkles to iron out.

"You know when a team is ready to go, when we're not making mental mistakes," Whitner told reporters during Tuesday's Super Bowl Media Day, according to the San Jose Mercury News. "I really haven't seen that yet. We still have work to do."

It's not clear whether Whitner's concerns stem from the offensive or defensive side of the ball, where Whitner's veteran presence and 62 total tackles helped the 49ers win the NFC West and claim a first-round bye in the NFC.

But the seventh-year veteran out of Ohio State is likely as good a source as any to diagnose whether the 49ers are ready for the schemes the Ravens are sure to bring on both sides of the ball. Despite the initial pessimism, Whitner thinks that, although the 49ers aren't quite ready yet, they're nearly there.

"I believe we are close," Whitner said. "We're close."
