I need help with some fantasy football trades!!!?

For sure no on the first one even thou its tempting because Addai is gonna tear it up. I almost say yes to the second one only because Roddy should be good and Chester does back up AP if you keep him. IF u do the first one thou then dont do the second one. Roy should be better than Roddy but not by much. I would say no to the first and yes to the second.
