For the fourth straight season, Adrian Peterson did not carry the ball in any of the Minnesota Vikings' exhibition games.
The question is, does it matter?
As Peterson has gotten older, he obviously is looking to conserve his body and isn't worried about getting any game conditions in before the start of the season.

But in each of the last three years -- sans a preseason carry -- Peterson has not topped 100 yards in Minnesota's regular-season opener. In the five seasons Peterson did see action in an exhibition (or two or three), three of those times he rushed for over 100 yards in his regular-season debut and 98 in another.
Of course, those three 100-yard games also occurred in his first three years in the league, when his legs (and body) were fresher.
Maybe there's nothing to be made of it, or perhaps that preseason work does help after all, no matter your age. Here's the preseason and regular-season numbers of Peterson year-by-year.
