FF Librarian and FSTA RB rankings accuracy contest

46 sites participated in the rankings accuracy challenge that is run in conjunction with the Fantasy Sports Trade Association (F.S.T.A.). The results of the contest were revealed a week ago at the F.S.T.A. Winter Conference. Refer to the New York Times blog article below for even more information:

Web sites that were interested in participating in the contest were asked to submit their preseason rankings for the top 25 quarterbacks, 50 running backs, 50 wide receivers and 20 tight ends based on the standard scoring system below:
Passing Yards (25 yards per point)
Passing Touchdowns (4)
Rushing Yards (10 yards per point)
Reception Yards (10 yards per point)
Rushing & Receiving Touchdowns (6)
Interceptions & Fumbles Lost (-2)
Using Fantasy point totals for QBs, RBs, WRs and TEs based on the above scoring system, the Fantasy Football Librarian (aka Sara Holladay ) created an end-of-season ranking for each position by using FFToday.coms statistics page. She took the difference between each site’s preseason positional ranking and the end-of-season positional ranking and squared that difference in order to penalize large errors in rankings. Then she summed those squared differences and averaged them for each position, which determined which site’s positional ranking was most accurate.
Finally, to determine which site was the most accurate across all four positions, she summed each site’s average squared difference for the four positions and divided by four for the four positions analyzed to see which site had the lowest average. The site with the lowest average was the most accurate site.
That is a whole lot of math my friends. And the outcome?
The FFLibrarian/FSTA 2011 fantasy football RB rankings accuracy results are as follows:

1. (Jamey Eisenberg)
