At the beginning of the 2009 NFL season, the consensus among football fans and fantasy owners was that Adrian Peterson was the best running back in the league.
After two monster seasons, the Minnesota Viking had established himself as an elite force, and arguably one of the strongest to ever play the position. It seemed that the next five plus years would be dominated by Peterson, as he'd hold the crown as the league's best RB.
AP has had a very respectable 2009 season. Not only is his team one of the best in the NFC (largely due to his stellar play), but his 17 touchdowns and his 435 receiving yards are both career highs.
It looks as if Peterson should finish the season with the most all purpose yards of his career, leading many to believe that he would still hold the crown as the NFL's top running back.
This would normally be the case, if not for the incredible season that Chris Johnson has had. Johnson, now in his second year in the league, is having a season that few other RBs in the history of the sport have ever had.
Not only are his 1,872 yards a league high, but he holds and outside chance at breaking the all-time record for most all-purpose yards in a season. With 483 receiving yards to go with his rushing performance, Johnson has simply been phenomenal.
