How should I start my team this week? Need help please.?

Only six teams have allowed fewer fantasy points to RBs than the Giants. Jacobs has some potential since he gets the ball at the goal line, but the Cowboys aren't far behind the Giants in defending against opposing RBs. I would sit Felix Jones this week and play Thomas Jones who is having a nice year and has a much better match up. Similarly, I would sit Moss against the Bears who have allowed 878 receiving yds, but only 2 TDs by wide receivers. Moore is having an excellent year and the Browns have already allowed 1000 receiving yds and 9 TDs by wide receivers. I would also keep Colston in the lineup.
