The saturation of the market for online fantasy football content presents plenty of positives and negatives.

On the upside, there’s no shortage of free material available for anyone who doesn’t feel like purchasing a subscription. On the other hand, it can be tough to navigate the myriad options to find the path to quality advice.

In addition to the rise in popularity of the FF Librarian and the introduction of TodayInFantasy.com, we’ve started to see a few outlets pop up that want to measure the credibility of the folks coming to you wearing “fantasy expert” badges.

One such effort is a joint venture by new sites FFSpin.com and FantasyFootballCrystalBall.com, in which the folks behind them will measure the accuracy of weekly by-position player rankings from the whole 2009 season.

FF Spin founder Scott Pashley said they are still collecting participants and that they hope to grow the effort further.

“Moving forward we hope to do projections and measure the accuracy down to the tenth of a point,” he said.

This current process appears similar to that performed by FantasyXPERT.com on a weekly basis last season and is a week-by-week cousin of the FF Librarian’s Accuracy Challenge, which measures the accuracy of full-season player rankings.

Any sites interested in getting their 2009 weekly rankings into the competition should contact Pashley ([email protected]).
