I'm not sure I would do the first deal. I can't speak for the keeper aspect of it, But I think you are giving too much in Thomas and Keller. Williams may never come around in that horrid offense. I like the second one for you in case Jones continues to be the main guy. Unless the other team is really hurting for a WR, I think he could get better than Garcon for Jones at this point.
