The free-agent pool for your fantasy football league is likely lacking many quality options, but that doesn't mean there aren't a few sleepers who can help you in Week 8 and beyond.
Stefon Diggs was likely one of the bigger pickups of the week, while Darren McFadden, James Starks and Alfred Blue should all be owned in most leagues. If those players are still available, they should be your first choices on the waiver wire. Assuming they are gone, however, you can look for a few lesser-known players who are likely still available in your league.
