5 Keeper Candidates Sure to Win Your Fantasy Football League in 2013

4,017 rushing yards. 37 touchdowns.

Going into the 2012 season, there is no way anyone predicted that the three rookie running backs, Alfred Morris, Doug Martin and Trent Richardson would combine to put up these numbers.

If they were able to put up these types of statistics their rookie season, imagine how dominant these three running backs are going to be in 2013.

With the 2012 fantasy football season just about over, here is a list of five keeper candidates sure to win your fantasy football league in 2013.

Alfred Morris, Washington Redskins

From being drafted in the sixth round of the NFL draft to winning the starting running back job for the Washington Redskins, Alfred Morris has been one of the best players in all of fantasy football.

As a rookie, Morris ranked second in both rushing yards and touchdowns with 1,613 yards and 13 touchdowns.

Chances are, Morris was taken in the very late round of your fantasy football draft or he went undrafted. Fantasy owners must keep Morris for not only 2013, but for at least the next five years. Mike Shanahan always makes his starting running back a fantasy football stud, so expect Morris' high level of production to continue.

Doug Martin, Tampa Bay Buccaneers

251 yards and four touchdowns.

That's right. Doug Martin put up those historic numbers in a single game as a rookie this season. 

Martin was another rookie running back who proved that he could easily adjust to the NFL level, running for over 1,400 yards and scoring 12 touchdowns. Another impressive statistic about Martin is that in every single game this season he never had less than 10 touches in a game.

With Martin being the focal point of the Tampa Buccaneers offense, expect him to continue to get 20 touches per game for at least the next five seasons.

Dez Bryant, Dallas Cowboys

In the second half of the season, there was no better wide receiver in the NFL than Dez Bryant.

After getting off to a sluggish start, catching only two touchdowns in his first eight games, Bryant went on a tear and finished the season with 12 touchdowns.

Bryant finally stepped up his game and proved to everyone why he was so highly touted coming out of college. Now that he has taken over the No.1 wide receiver position for the Dallas Cowboys, expect Bryant to become a top-five fantasy receiver.

A.J. Green, Cincinnati Bengals

Everyone knew after A.J. Green's rookie season in 2011, in which he made the Pro Bowl, that he was going to be an absolute stud in the NFL.

Green did not let any fantasy football owners down in 2012, putting up huge numbers. Not only did Green finish with over 1,300 receiving yards and 11 touchdowns, but he also scored at least one touchdown in nine straight games this season.

Green has solidified himself as a top-three fantasy wide receiver heading into 2013 and will become the best receiver in fantasy football within the next three years.

Trent Richardson, Cleveland Browns

Though the Cleveland Browns continue to struggle, at least they finally have a legit offensive weapon to build their offense around.

Trent Richardson had a sensational rookie season, scoring 12 touchdowns. What made Richardson so great in fantasy football was the fact that he got so many touches every week. Richardson had at least 15 touches in 12 games this season.

With no other offensive weapons on the Browns, Richardson is going to continue to get the rock at least 20 times per game in 2013.
