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 rankEdgerrin James- 1st, 2ndClinton Portis- 4th, 5thFred Taylor- 4th, 28th (injured, 10 games)LaDanian Tomlinson- 7th, 3rdWillis McGahee- 9th, 13thEddie George- 8th, 12thJamal Lewis- 16th, n/a (injured, 0 games played, but he ranked 12th in his third year)Corey Dillon- 8th, 17thKarim Abdul-Jabbar- 9th, 6thDomanick Williams (nee Davis)- 14th, 5thWarrick Dunn- 13th, 19thAnthony Thomas- 13th, 33rd (injured, 12 games)Kevin Jones- 21st, 31st (injured, 13 games)Caddilac Williams- 19th, 39thRonnie Brown- 23rd, 25th (injured, 13 games)William Green- 27th, 47th (injured, 7 games)Ricky Williams- 27th, 18th (injured, 10 games)Travis Henry- 28th, 8thRon Dayne- 29th, 27thThrowing 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?
