I agree with you on Rothwell and Nurmagomedov but I gotta go with my heart and pick the Phenom. Safarian is highly touted, was suppose to win TUF: Brazil, but Dolloway is a very accomished wrestler and will look to utilize what will be, IMO, a large grappling advantage.
So my picks: Belfort, Dollaway, Rothwell, Nurmagomedov.
Wouldn't it be awesome if Nurmagomedov got another slam KO?
