Which of these 2 for my Flex?

The Carolina D is one of the better ones againbst WRs. Only the Chargers and Saints have allowed fewer fantasy points per week to opposing WRs. However, they still have allowed 737 receiving yds and 6 TDs. While Detroit is dead last in fantasy points allowed to RBs, that doesn't necessarily translate to points for Greene who hasn't done much to inspire confidence in him yet. I would start Moore rather than counting on Greene to suddenly start performing. Tomlinson is the guy that will benefit from the Lion run D.
