After a disastrous sophomore season, Todd Gurley has bounced back in a huge way. Through four games, he might be a better player than he ever was as a rookie, racking up 596 yards from scrimmage.

Gurley is currently No. 2 in the NFL in rushing, leads the league in first downs with 22 and has carried the ball more than all but one player (Le’Veon Bell). Everything about his hot start to the season is eye-popping, but it’s even more impressive when you consider how few players have matched his numbers through four games.

Only two running backs in NFL history have ever had 575 yards from scrimmage and seven touchdowns through four games: Hall of Famers Emmitt Smith and Jim Brown — two of the best backs the league has ever seen.

Gurley has 362 yards rushing (4.2 yards per carry) and 234 yards on 20 receptions. Entering this season, he had as many touchdown receptions as you did, but through three games, he already has three. That’s not only the most among all running backs, it’s the third most in the NFL right now.

Every aspect of his numbers is impressive no matter how you break them down. When you stretch them out over 16 games, you realize just how unheralded his performance has been.

Todd Gurley pace: 344 carries, 1,448 yards and 16 TDs.

No player in NFL history has ever recorded 1,400 yards rushing and 900 yards receiving in a single season. Marshall Faulk, of course, came close in 1999 when he had 1,381 yards on the ground and 1,048 yards receiving.

To be fair, Gurley isn’t likely to keep up that pace. He has a brutal stretch of games coming up, facing the Seahawks, Jaguars, Cardinals, Giants, Texans and Vikings all in the next six weeks. Still, Gurley has a legitimate chance to surpass 2,000 yards from scrimmage and 20 touchdowns this season.
