Re: Alex Smith vs. Colin Kaepernick
And really, the main reason I would go with Alex if he were healthy, you can't go back.
If you sit Alex Smith, the QB that got you a play-off win last season (was it two? did they get to the NFC Championship game?) The guy that got you to 7-3, you can't go back.
If something happens to Kaepernick then you'll have Alex Smith out there "trying to prove" something he doesn't need to. He should just be allowed to play his game.
If something happens then, you can always go back to Kaepernick who is already trying to prove something.
