When Murray is healthy, he's one of the NFL's top 10 backs. The problem is, Murray has missed 11 games over his three seasons with the Cowboys. He didn't get as many opportunities as most of the other backs on this list did in 2013, but when Murray's number was called, he averaged 5.2 yards per carry. Over Murray's career, only Peterson, Charles and Buffalo's C.J. Spiller are averaging more than Murray's 4.9 yards per carry. Give him more than 15 carries per game and his numbers could be very impressive. Spiller, Frank Gore, Maurice Jones-Drew and a few others could've also made this list.

His first two years in the league have been more impressive than almost anyone could have expected. Only Peterson has more rushing yards during that period of time. Mike Shanahan's success with running backs during his days in Denver certainly seemed to carry over with Morris. The former sixth-round pick has already rushed for 2,888 yards and 20 touchdowns.

A Super Bowl hangover seemed to hold back everyone in Baltimore this season. Rice failed to reach the 1,000-yard mark for the first time since his 2008 rookie season. I expect a bounce back year in 2014 with something closer to the 1,266 yards he averaged over the previous four seasons.

An outstanding weapon in both the running and passing game. Forte rushed for a career-high 1,339 yards and nine touchdowns in 2013 while also catching 74 passes for 594 yards and three more scores. He seems to be a perfect fit for Marc Trestman's offense, so the next few years could be just as impressive.

Like Charles and the next two backs on this list, Johnson was a player the Cowboys could've drafted instead of Felix Jones in 2008. Since that draft, only Peterson has rushed for more yards than Johnson, who has topped the 1,000-yard mark every year of his career, including a 2,006-yard season in 2009. Felix Jones has never had a 1,000-yard season and has 2,912 yards for his career.

How did a player this talented go undrafted? Twenty running backs came off the board in 2009 and McCoy is the only one to make this list. Back surgery caused Foster to miss the second half of this season as he was on pace for his fourth consecutive 1,000-yard season. Between 2010 and 2012, Foster rushed for 4,264 yards and 41 touchdowns.

The most physical runner in the game. Lynch has rushed for over 4,000 yards during the last three seasons as Seattle's featured back. His 35 rushing touchdowns during that time are most of any back. It's hard to believe Seattle got him from Buffalo in 2010 for a pair of draft picks.
Among the top five rushers in the game in the three of the last four seasons, Charles is as versatile as any runner in the league. On top of rushing for 1,287 yards and 12 touchdowns this season, the former Texas Longhorn standout also caught 70 passes for 693 yards and seven TDs.

Only Peterson has rushed for more yards than McCoy over the last four seasons. The former second-round pick, who rushed for over 1,600 yards in 2013, is such a creative and elusive runner that he is considered the closest comparison to Hall of Famer Barry Sanders.

Since entering the league in 2007, Peterson has rushed for 10,115 yards. During those seven seasons, no other player has rushed for even 8,000 yards. Peterson has rushed for 296 yards in a single game and 2,097 yards in a single season. This was an easy choice.
