People keep mentioning this "sophomore jinx", or this "sophomore slump". Can anyone provide any decent examples of this in action? Other than Michael Clayton, of course. I mean, it's pretty well established that QBs make a bigger jump between year 1 and year 2 than at any other point in their careers. TEs and WRs almost never amount to anything as rookies, so I don't really see how they could "slump" in year 2. This leaves RBs as potential victims of this "sophomore slump".
From 1996 to 2005, there were 23 RBs with 200+ carries in their "freshman year". Here's the list, sorted by fantasy rank, followed by their fantasy finish in their first and second seasons. I've left off guys like Mike Anderson and Dominic Rhodes who were backups in their second year.
Name- Year N rank, Year N+1 rank
Edgerrin James- 1st, 2nd
Clinton Portis- 4th, 5th
Fred Taylor- 4th, 28th (injured, 10 games)
LaDanian Tomlinson- 7th, 3rd
Willis McGahee- 9th, 13th
Eddie George- 8th, 12th
Jamal Lewis- 16th, n/a (injured, 0 games played, but he ranked 12th in his third year)
Corey Dillon- 8th, 17th
Karim Abdul-Jabbar- 9th, 6th
Domanick Williams (nee Davis)- 14th, 5th
Warrick Dunn- 13th, 19th
Anthony Thomas- 13th, 33rd (injured, 12 games)
Kevin Jones- 21st, 31st (injured, 13 games)
Caddilac Williams- 19th, 39th
Ronnie Brown- 23rd, 25th (injured, 13 games)
William Green- 27th, 47th (injured, 7 games)
Ricky Williams- 27th, 18th (injured, 10 games)
Travis Henry- 28th, 8th
Ron Dayne- 29th, 27th
Throwing out all of the players who missed significant time (3 games or more) due to injury, the players ranked 10.9 on average in year N, and 11.7 in year N+1. Explain to me how, exactly, this is evidence of a slump and not simple regression to the mean?
