CJ Spiller: Buffalo Bills RB Will Render Fred Jackson Useless to Fantasy Owners

Buffalo Bills running back C.J. Spiller has been unstoppable through the season's first two weeks, leading the NFL in rushing and earning praises from happily surprised fantasy football owners across America.

Unfortunately for fantasy owners with former Bills starting RB Fred Jackson—who is out with a knee injury—on their roster, Spiller's productivity will ultimately render the banged-up veteran useless in terms of fantasy production.

Spiller is averaging 10.1 yards per carry through two weeks. That average is unheard of after one game in today's NFL, let alone after two. He has 292 rushing yards and three touchdowns already to go along with five receptions for 72 yards.

Needless to say, Buffalo boasts the No. 1-ranked rushing attack in the NFL in 2012. Despite Jackson being out with an injury, the team is averaging slightly under 200 yards on the ground per game. 

Spiller, who is in his third year out of Clemson, averaged 3.8 yards per carry as a rookie before boosting that mark to 5.2 yards per carry in 2011. With only 210 career rushing attempts, Spiller is fresh; much fresher than Jackson, who has nearly four times as many career carries. 

Sure, Jackson was a 1,000-yard rusher in 2009 and averaged 5.5 yards per carry last season. However, he has proved to be injury prone, missing six games last season. He is far less explosive than Spiller in the running game.

Spiller is also six years younger than Jackson and will no doubt continue to be Buffalo's first choice in the backfield as the 2012 season wears on. For fantasy owners hoping to slide Jackson into their RB spot once he returns from injury, Spiller's breakout performance has been nothing short of a nightmare.

Unfortunately for those unlucky owners, it won't get any better any time soon. 

In the NFL, where one game can elevate a player to star status and cause another to be totally forgotten, injuries can both alter careers as well as fantasy seasons in this case. 

Not only will Jackson continue to miss time because of his knee injury, but once he returns, his snaps will be limited and his fantasy production will be hampered by the presence of Spiller. 

Unless you're a Bills fan with Fred Jackson on your fantasy roster this fall, you should be rooting for opposing defenses to shut down Spiller from here on out.
