I think you may have some RBs to spare. If one of your current handcuff guys gets injured, chances are his backup will still be available. Plus, you have a lot of solid ones anyway.

...AND although Flutie played well today, it wouldn't surprise me to see Brees back later this season. San Diego isn't in the playoff chase and might want to give their QB of the future another shot to see what they need to do for next season.
Keep Maddox.

I agree with Ronald to keep Maddux but I still think you should pick up Flutie. I'd drop Foster. I don't think Davis will be out another week and he didn't look too impressive either.
