Thanks for the help!
I think that you're correct in leaning toward Hasselbeck. They will likely be playing from behind, which is never a bad thing...plus, NE secondary has proven to be suspect. Unlike the beginning of the season Hasselbeck has some weapons at his disposal. As far as Rivers is concerned, he just hasn't played very well lately. Also, the one glimmer of light that the Raiders have is their secondary. Hope this helps.
