To be clear, I didn't mean they would sign Kaepernick, but someone like him who has experience. I will be surprised if they are willing to bring in the controversy he represents.
As for Hundley, I think he will be fine after a week practicing with the starters, and with a game plan that expects him to be carrying it out.
Of course, if Taylor, Bulaga and Bakhtiari are all out he may not have much chance to do anything.
