Here's what I think:
Big Ben Cutler
So you are getting hustled on just that and then only getting bryant and mcfadden for foster. Trading him fosters handcuff should be worth a bit more too. You can get a better offer than that just hang on. As far as your other trades, you won't get any value trading jennings away right now, it's worth it to hang on to him. I personally like charles over gore this year, so maybe try to get harvin and charles for foster.
