I would go with Foster. Moore is not going to do much with Heinckle. Foster probably has a better chance of more points. I had DJ Moore and dropped him this week. I would only expect 5-8 points even in PPR.
Go Moore! What's not being discussed is that Cam wasn't taking snaps over the past few weeks during practice ad that was given to the backup. The backup will not be Cam by any means but he knows the offense.
