Only two running backs in the history of the NFL have gained 1,000 yards both through the air and on the ground in a single season, those backs are Marshall Faulk and Roger Craig.
Ravens running back Ray Rice has 297 rushing yards and 242 receiving yards through four weeks of the regular season, meaning he is just barely off the pace of finishing with 1,000 yards both on the ground and through the air.
Rice has topped the 1,000 yard rushing mark in each of the past two seasons, and with Willis McGahee out of the picture, injury is the only problem that will keep the elusive back from approaching the milestone in 2011.
The challenge will be getting to 1,000 receiving yards. In 2009, Rice set career bests in receptions (78) and receiving yards (702), and defenses have responded by paying a lot more attention when Rice sneaks out of the backfield.
As it stands now, Rice is on pace for 968 receiving yards, which would leave him just 32 yards from his goal. He would have to average 63.2 receiving yards per game, while continuing his pace rushing the ball.
