Do you believe in the sophomore slump? Or do players instead tend to get better in their second year (having the benefit of offseason camps, knowing the offense better, adjusting to the speed of the pro game and whatnot)?
It's a timely question this year because three running backs come off great rookie seasons. Doug Martin, Alfred Morris and Trent Richardson. Should we all be targeting those guys? Or avoiding them?
I always like to look at the past numbers in these kind of situations. Not that they necessarily reveal the truth, but they provide us some feedback. They show how things turned out in similar situations in the past.
For this one, I pulled out the top 20 rookie running backs of the last 30 years. I left Jamal Lewis and Robert Edwards out, since they both got hurt long before the start of their second seasons.
Of the 20 backs I've listed, only four came back the next season and finished with more yards (run-rec) and more touchdowns. Only six of the 20 (30 percent) finished with better fantasy stats.
As a whole, about half of the guys were pretty good. Half gained at least 1,500 total yards, and 11 (one more than half) scored double-digit touchdowns.
If I were a betting man, therefore, I'd say it's a safe bet that at least one of our three backs (Morris, Martin, Richardson) will fall well short of expectations. But that's the nature of the running back position, where injuries are common.
This same chart is listed at the Facebook page, and it's prettier there, with some colors worked in.
On this chart, the rookie numbers on the left (and I've got them in declining order, with Eric Dickerson having posted the best overall numbers using the scoring system of 6 points for touchdowns and 1 for every 10 yards). To the right of each player's name is his production in his second year.
Two players got hurt very early in Year No. 2 (Curt Warner, Ickey Woods). And Mike Anderson became a backup (with Terrell Davis returning from an injury). For the Herschel Walker stats, I adjust his second year numbers up to account for the player strike in 1987 - he played in only 12 games.
