In nine NFL seasons, Adrian Peterson has played all 16 regular-season games four times. He did it in 2008 with a career-high 363 carries, as well as 2009 (314), 2012 (348) and last season (327) at age 30. So what can we assume, carries-wise, if the now-31-year-old freak of human injury and aging stays healthy enough to play all 16 games this season? First, I asked offensive coordinator Norv Turner Tuesday if he has seen anything indications of Peterson’s advanced NFL age. “From this camp, I have not seen anything,” Turner said.
