Adrian Peterson always has been a freak of nature. It's not just the fact that he's one of the most productive running backs in NFL history, but also the staggering speed he's been able to recover from devastating injury.
The prime example is when Peterson tore his ACL during a Christmas Eve game in 2011 only to return in time for the season opener next year, where he ran for 84 yards in two touchdowns.
Only the most physically gifted among us could do something like that.
So when Peterson goes out and takes 22 carries on Sunday, at 35 years and 190 days of age, we might take that for granted.
