Peterson To Break Smith's All Time Rushing Record?

Can Adrian Peterson break Emmitt Smith's all time rushing record by 2017?  Nope.  Break it?  Yes.  By 2017?  No.  He would have to average 120 yards per game . . . In the second half of his career.  Not gonna happen.  If you have thoughts on this, lay 'em on me.
