Hopefully you didn't start either of the Dallas backs, though Felix did manage a score. If it's standard scoring, I don't see how you can do anything but start FJax. Check his status, but I think he's a go for this week. If it's PPR, Rodgers isn't a bad start, but I think you have to temper expectations because like you said, they talk about it a lot but it doesn't happen. Don't forget Snelling is in that mix too, and that Tampa run defense is pretty solid. Starks might be a sneaky little play, and to be honest I'd drop Thomas for him because his upside is greater, even if you don't start him this week.
So....FJax > Starks > Rodgers standard. Rodgers > FJax > Starks PPR. Good luck!
