There was a time in the NFL where Adrian Peterson was the undisputed No. 1 running back in the entire league. He ran for 2,097 yards in 2012, he broke tackles at will and was constantly the top pick in fantasy drafts. However, those days are long gone.

Or are they?

It appeared like Peterson was done after a 2017 season where he bounced around between the Arizona Cardinals and New Orleans Saints with lower production. But the future Hall of Famer absolutely crushed his former team on Sunday. 

The strangest part of the entire performance was his contribution in the passing game. Peterson had 70 receiving yards, matching his output for the entirety of 2017 and coming close to half of his career seasonal average of 173 yards. He also added 96 rushing yards and a touchdown to suddenly appear as another viable fantasy option again. 

Peterson will be splitting touches with Chris Thompson, who looked equally as impressive on Sunday against the Cardinals, but mostly in the passing game. Peterson got 25 carries compared to Thompson's five. 

He also got one more after the game ended:

So, Peterson appears to be productive again, but it's far too early to put him back up in the top tier of running backs. At the moment he's probably a fringe RB2 and more like a flex. Remember he may have put up good numbers in Week 1, but that was against the Cardinals, who are primed to be one of the worst teams in the league this season. And even then, he averaged only 3.7 yards per carry. 

If he continues to perform against the Colts next week and followed by the Packers the week after, then he can be considered RB2 or even an RB1. But at the moment let's just enjoy the fact that one of best players in NFL history still has a little gas left in the tank.
