Yeah dude, Sergio Kindle would be a better pick than Sam Bradford at #17, ok...
I wouldn't trade both picks to get Clausen and I don't think they can realistically get to 1 or 2 for Bradford, but if those guys fall in your lap you have to look at it.
Next year is next year. Nobody has any idea where the Niners will be drafting and who may be available. People thought Jevan Snead was going to be a top 5 pick at this time last year. The niners division will be really, really bad. They will have to stink it up royally (like, more than I can possibly imagine) to be in the position to draft a franchise QB next season.
