Damn tbh honest Detroit has a great front 7 and is tough against the run, but Niners need Gore to run the game. But, TB is without McCoy, their best DT against the Run. Look what SF did to TB, now look at a high power offense like NO and imagine what their going to do. I'm one for never sitting a tier 1 RB like Gore, but I think Sproles is going to have an amazing game tomorrow.
Tough Call, but like everyone else has been saying since you are not in a PPR league.. I'd say Gore because he is the Niners only hope to score and get yards besides their D
