Adrian Peterson says he’s still the NFL’s best running back at age 30 and could have played in the pros at 18 had league rules allowed.

In a conference call with Denver media Wednesday, the Minnesota Vikings running back said he believes he could have gone straight from high school to the NFL instead of spending three years at the University of Oklahoma.

He said LSU running back Leonard Fournette must be good because everyone seems to be comparing the two.

And he had a hard time naming a better running back in the NFL today although after some thought he did say, “Peyton Manning’s got some nice moves.”

Peterson’s Vikings (2-1) visit Manning’s Broncos (3-0) this weekend.
