NEW ORLEANS -- For his next act, San Francisco 49ers quarterback Colin Kaepernick will try to accomplish what Andrew Luck, Peyton Manning and Tom Brady could not pull off in these NFL playoffs. Kaepernick will try to lead his team past the Baltimore Ravens.No bar appears too high for Kaepernick to clear after the second-year pro helped the 49ers overcome a 17-0 deficit at Atlanta in the NFC Championship Game. But as Super Bowl week cranks up, Ravens QB Joe Flacco has been cast as the "hot" quarterback.
