After exploding for six receptions, 118 yards and two touchdowns against the Dolphins last week, Roberts stayed pretty quiet in Week 5. He finished with five catches for 39 yards in a 3-point performance from the Cardinals' offense.
Fantasy Impact: It was hard to believe Roberts could sustain his huge numbers from Week 4. Sure enough, Arizona's offense struggled mightily against the Rams, and Roberts caught just half of his targets. He has the tools to be a reliable receiver, but Kevin Kolb running for his life doesn't translate well to big numbers in the passing game. Don't give up on Roberts. Just understand his numbers will fluctuate often throughout the season.
