Adrian Peterson didn't get his asking price from the Vikings, and won't from any other NFL team, for that matter. More than an indictment of the 31-year-old who spent most of the 2016 season on the shelf, Peterson's salary is far removed from that of the modern-day running back. His cap hit was $18 million, with an average annual salary of $14 million. Those monster paychecks are a thing of the past for him now. So what can he expect when his free-agency search starts in earnest next week? Based on salaries listed by Spotrac, here's a yardstick.
