Under no circumstance should this team take a RB in Round #1, since it's a position you can plug-and-play in the later rounds. I'd take Najee Harris in the second round without blinking as that dude has so much athleticism and versatility. I would question a WR at 16. As I've said, a franchise QB can get the most out of his receivers, especially if Hop and Green are your two top options, and Kirk isnt a slouch. It's on Kyler to make them better or hit their potential.
If Horn, Surtain and Farley are gone by 16, then we have a conundrum on our hands, at which point, Keim should do everything to trade back.
