I like both the Roby and Edelman pick. My only concerns are that, while the former is said to be taking over at FS for the Broncos next year it is going to be hard to for him to improve as a CB. He did, however, prove he can be a decent starter on the outside, especially as a press corner.
Edelman issue is mainly drops, because the foot injury cannot be overstated. He's still a young and sharp route-runner.
