As the NFL has transitioned into more of a passing league, running backs have taken a back seat in importance to a team. Last year's Super Bowl champions, the Green Bay Packers, lacked any sort of running game for the majority of the season.
The first-round of the 2011 NFL draft only had one running back taken, Alabama's Mark Ingram. More and more teams are placing the future success of their franchise on their quarterback's shoulder.
Of course there are still some teams that depend heavily on their running backs. Adrian Peterson, Maurice Jones-Drew and Chris Johnson are still the focal points of their team's offense. However, this is certainly not the norm.
There is still a need for quality running backs and there are plenty of teams looking for one and plenty of teams looking to trade one. Here is a look at the 10 best running backs on the trading block and where they might end up.
