Yesterday, Bob Ford wrote DeMarco Murray and, how his 2014 season stands out as a career outlier. Today, I want to look at where it stands among the biggest year-to-year declines.

I looked at all players who rushed for at least 5 games in consecutive years, and rushed for at least 60 yards per game in the first season. For example, Murray rushed for 1,845 yards in 2014, an average of 115.3 yards per game. Last year, in 15 games, Murray averaged only 46.8 rushing yards per game. That’s a dropoff of 68.5 rushing yards per game, which is the second most in NFL history. The first? That honor goes to Lee Suggs.

Suggs was a star at Virginia Tech, rushing for 27 touchdowns in 11 games as a sophomore at Virginia Tech before tearing his ACL as a junior. In his senior year, he had another great season, rushing for 1,325 yards and 22 touchdowns. He was a 4th round pick of the Browns in 2003, where he served as the team’s backup. In ’04, he stole the job from William Green, and rushed for over 100 yards in each of Cleveland’s final three games. He averaged 74.4 rushing yards per game in ’04, but lost his job to Reuben Droughns in ’05. As a result, Suggs saw his average decline by 72.5 yards per game, an even more dramatic dropoff than Murray.

So, is there any hope for Murray to turn things around? I looked at how all of those running backs then fared in Year N+2 (excluding those inactive during that year). I’ve sorted those backs in reverse chronological order. Let’s use Ladell Betts as an example. He averaged 72.1 rushing yards per game in 2006, then 20.9 the following year. In 2008, he rushed for just 206 yards in 13 games, a 15.8 rushing yards per game average. So Betts is an example of a player doing even worse in year three, rather than having some sort of regression to the mean.

On average, these running backs averaged 82 rushing yards per game in Year N, 24 yards per game in Year N+1, and then just 29 rushing yards per game in Year N+2. There are a few positive examples Murray supporters could look to: O.J. Simpson sandwiched historically dominant seasons in ’73 and ’75 around a just pretty good year in ’74. But there are fewer bounce-back seasons than you might otherwise expect.
