As Adrian Peterson prepares for his 10th NFL season, he's coming off his third rushing title in large part because of the unyielding work ethic that still has him training for three to four hours a day at his gym in Houston.
He's working to stay ahead of a young generation of running backs who were raised on Peterson highlights. And in the case of Melvin Gordon -- the San Diego Chargers back who finished second in the 2014 Heisman Trophy voting and was selected 15th in last year's draft -- Peterson has a protege who has come to Houston this summer in the hopes of adopting some of the four-time All-Pro's tenacity.
Gordon, who ran for 641 yards, fumbled six times and missed two games because of a microfracture in his left knee during a trying rookie season. He contacted Peterson in February about training with him this offseason, the story said. Gordon has gone through some of the same drills, designed to improve his balance and proprioception after his injury.
