Return yards

I have Jabari Greer and Arenas in my req'd CB slots. However I just picked up Tramon Williams since my league gives a pt for every 10 return yrds and 7pts for a return TD. Should I sub Williams for Greer this week?

Sorry, forgot to mention that I also have Kelvin Hayden on my bench.

Well, on average Tramon's return yards will probably get you about 2-5 extra points every week and he has the potential for good tackle numbers. The Bears figures to be a good matchup this week. However, Greer has Roddy White and the Falcons this week which is also a good matchup. I think Williams' upside is higher this week, but Greer is the safer play. It depends on how you feel going into this week. If you need to put up a lot of points go with Williams, if you are going to play conservative go Greer. Hayden is a fairly safe option as well, but I'd give Greer the edge cause of the Roddy White factor.
