Advice for a Bye Week Spot Start

I need a second RB to start due to losing Cook, Carson, and Freeman and Thompson being on Bye. Fortunately I still have Hunt to lead my RBs but the real question is RB2.

In a full PPR should I play Giovani Bernard, Johnathan Stewart, or pick up Elijah McGuire and play him?

Im a fan of mcguire for this week

Care to explain why? I have been debating between him and Gio the last couple days
