Roberts is coming off a big week against the Houston Texans. He had five catches for 72 yards and one score on eight targets. The performance was his best of the season. Roberts scored his first touchdown of the year during the bout.
Roberts' big game was due, in part, to fellow wideout Michael Floyd missing most of the action due to a shoulder injury. Floyd is back this week, so Roberts will return to a tertiary role. The Cardinals run mostly two-wide sets, meaning Roberts won't see enough snaps to rack up catches.
Fantasy impact: The Cardinals have actually been able to run the ball this season, but their offense isn't a powerhouse. There has been no word of Floyd being limited, so Roberts won't have much fantasy value again. If you picked Roberts up on a speculative basis, there should be a wide variety of available options who are better.
