7. Adrian Peterson, 2007, Vikings
The competition is fierce at the no. 7 spot, but Peterson gets the edge over the likes of Champ Bailey, Sterling Sharpe, and Phil Simms, which isn’t exactly bad company. The fact that Peterson is still playing in 2019 doesn’t hurt his case. He has continued to be a valuable part of NFL teams deep into his 30’s, which is something few running backs can say.
After winning Offensive Rookie of the Year honors, Peterson went on to lead the NFL in rushing three times and win NFL MVP honors in 2012. At this point, he’s the old man in the backfield just hanging on, but when he was first drafted, Peterson was arguably the best player in his class and one of the biggest difference-makers in the league during his first seven seasons.
