For Flex, I like CJ2K. I usually prefer a RB in the flex spot as they typically get more touches than WRs, which means more potential for points. Also, Johnson has been playing much better recently so that trend should continue.
For QB, I would sit Vick in both cases. Eli is much more consistent and is equally capable of putting up big numbers though he doesn't have nearly the turnover risk that Vick does. Ben has a terrific matchup with a weak Skins pass DEF and they should be throwing a lot to take advantage of that.
