Fantasy Upside
Adrian Peterson is back! After playing in only one game last season due to a suspension, Peterson returns and is expected to do big things. In all eight seasons he's played (excluding 2014), he's scored at least 10 touchdowns on the ground. He's also rushed for over 1,000 yards in all but two seasons (finished with 970 in 12 games in 2011). Some could also view taking a year off from the physical nature of an NFL season to be a good thing for Peterson in terms of his health. He should be rejuvenated and ready to spring into action.
Fantasy Downside
Peterson's legal troubles still loom somewhat. He has to make sure he doesn't get in trouble again, or else he's looking at another suspension. He's no spring chicken, either. Peterson is 30 years old, and running backs tend to go downhill once they reach this age. It remains to be seen if he's still the incredible back that rushed for over 2,000 yards not that long ago.
Bottom Line
Peterson is one of the best in the business when he plays. If he's healthy and not facing a suspension, he's someone you want in your lineup. He's never had a bad season, unless you count last year. He should be viewed as a first-round draft pick and one of the anchors of your squad.
