I'd be much more worried about Alex Smith, but just don't think Kaepernick can make enough plays with his arm to win this game. Rodgers will have a tough slog against that defense, but can score just enough points to win.
Kaepernick hasn't really been the problem, some of the 49ers best players have gone down with injuries in the past few weeks. Harbaugh doesn't really seem to have managed the roster that well in retrospect.
And there are similarities because these teams weren't quarterback centric either. Not in the sense that the quarterbacks didn't need to play well, they just weren't asked to be the focal point all the time and do everything. Kaepernick is plenty good enough to be a Super Bowl winning quarterback with as much talent as the Niners have in most areas. Of course when you have the best quarterback in the league like the Packers, you always got a pretty good chance regardless of the opponent.
The battle of the Crabtrees! This is a tough game to pick. I think if the Packers weren't finally healthy, I would probably take the 49ers. I think it will be close. I can see it going either way. If Mason Crosby continues to struggle he may lose the Pack the game. On the other hand, Kaepernick will have to play a hell of a game. Those deep balls will be harder with Sam Shields and Charles Woodson playing and healthy.
