Duke J or David Montgomery??
I’d go with a logic based decision. They’re both relative unknowns in their respective offenses so that’s a wash; both have other backs that could steal some of show, again on the surface a wash; but if you look at what you do know - PPR (Duke’s bread and butter in CLE was catching passes) so I’d lean ever so slightly that way in week one and wait and see on David Moppurtunity. Good luck!
