FANTASY TIP: Bills RB Devin Singletary hasn't done much on the ground this season, failing to reach 50 yards rushing in any of their first five games. But the Chiefs were shredded by Raiders RB Josh Jacobs last week, and they tend to give up yards to running backs in the passing game. Singletary had nine catches for 78 yards and a touchdown a few weeks ago against the Dolphins, and he has 18 catches for 145 yards on the season.
