Peterson fumbing vs. other great running backs

With everyone in the league knowing that AD only downfall is his inability to hang onto the ball. It is usually when AD is trying to get the extra yard or so. So many fans are enraged every time he fumbles the ball away. Peterson has many more positives than negatives. He strikes fear into every defense that he faces. The opposing teams usually stop AD in order to win the game.

There have been some great that have had issues hanging onto the ball earlier in their careers as well:
Great NFL running backs fumbles per season for his first 4 season as a pro:

Eric Dickerson averaged 12.25
Walter Payton averaged 8.75
Jim Brown averaged 5.75
Earl Campbell 7.75
Barry Sanders 6.25
Adrian Peterson first 3 seasons 6.67 average

With so many people thinking that AD needs to fix this problem quick or it many be time to start shopping for a running back. Peterson will keep trying to find ways to try to keep the ball in his hands and not on the ground.It is just surprising with what I hear of his bone crushing hand shakes. Maybe AD is graping the ball to tight and it is popping out. Who knows? We Viking fan will see if AD can fix his fumbling issues.
