Probably Hilton. He has a defined role in a strong offense. Edelman is in a better offense and is very "in" now based on Gronk's injury, Edelman's strong game and Lloyd continuing to disappoint. The problem is it's just not clear that Edelman's role will be all that substantial on Thursday much less beyond that. I can't imagine either as a keeper candidate, however, unless your league is more dynasty than keeper as neither is all that valuable.
2 round penalty to keep. Free agents have an end of draft position... Not able to keep any in first 2 rounds. Can keep 3, only one per position. E.g I have stl richardson or reece and kaepernik as strong keeper candidates. Hilton and edelman were undrafted.
