Both the 49'ers Quarterbacks suck,Kaepernick isn't much of an improvement over Alex Smith
Well Smith has struggled over the years, but was having a great season. The game before he got injured, he completed 18 of 19 passes.
Frankly I think Harbaugh's ego got the best of him. He drafted Kaepernick to be the QB of the future and then got surprised when Smith improved so much.
It's as if he is trying to prove he was right all along or something.
Having said that, it isn't over yet and Kaepernick may lead them deep into the playoffs. But I think Kae. would have to screw up pretty badly for Smith to be back in. Harbaugh may not be the type to be able to admit he is wrong.
