There are an ever-growing number of “experts” out here in fantasyland and a new segment of ranking-the-rankers type outlets cropping up. The FF Librarian, however, is heading into her fourth season of holding the pros’ opinions against them.

Sara Holladay, the aforementioned Fantasy Football Librarian — collaborating with Donnie Campbell of TheMostCredible.com and Bill Green of FantasyDispute.com — has announced the opening of Season 4 of her Accuracy Challenge and the third to be affiliated with the Fantasy Sports Trade Association.

As part of this challenge, anyone with an online fantasy football outlet and published rankings and/or projections can submit for judgment, with the results announced at the FSTA’s winter conference as well as reported via FFLibrarian.com and The New York Times‘ Fifth Down blog.

Rankings and projections are due before 8:30 p.m. Eastern Sept. 9, which is the approximate time for kickoff of the season-opening Saints-Vikings game (as if you didn’t know). Late submissions will be accepted, as long as the organizers can verify that the lists were published before the first game.

Entrants must submit rankings for their top 25 quarterbacks, 50 running backs, 50 wide receivers and 20 tight ends in Excel format. The template for projections submissions can be downloaded via the FSTA website.

Past overall winners included CBSSports.com in 2009, Fantazzle.com in 2008 and Ask the Commish in 2007, (under what appeared to be a different scoring format).

Rankings entries should go to fflibrarian@gmail.com.

Projections entries should be sent to FSTA.Accuracy.Contest@gmail.com, dc@themostcredible.com, greenbill@fantasydispute.com and fflibrarian@gmail.com.

A roundup of items recently posted on the FSB News page.

– The Fantasy Players Association website passes along word that the Fantasy Football Players Championship has chosen RealTimeSports to host its leagues this year. The FPA also raises some concerns that the FFPC audience might have with the switch from previous host MyFantasyLeague.com.

– You’ve surely heard of the fancy new fantasy league-hosting product at NFL.com, but did you know that EA Sports will be providing the player projections for the full season and on a weekly basis?

– Have you ever played in a Yahoo! public league (or a free mock draft anywhere) and gotten annoyed by the person who screws the thing up with idiotic early picks? Well, FantasySharks.com is encouraging them. For the fifth straight year, the site is supporting a challenge in which participants join a “competitive” Yahoo! public league and draft a kicker and a team defense with their first two picks. The top prize (a sum of “sand dollars,” Fantasy Sharks’ fake currency) goes to anyone who can win their league.

– For accuracy in running back rankings, RotoWorld edged the field of participants who have been in the FF Librarian’s Accuracy Challenge for all three years it has existed. KFFL, however, has been dynamite over the past two seasons.

– In the wake of Yahoo! opening up its fantasy sports API, FanGraphs takes a crack at explaining a bit about what it is and what it allows you to do.

– Did you miss out on fantasy points when England’s clear goal was disallowed against Germany? Did you miss the game and the replay? Legos have your back.

A roundup of items recently posted on the FSB News page.

– This lengthy story from the Wisconsin State Journal takes a look at three fantasy sports companies based in the Madison, Wis., area — RotoWire, MyFantasyLeague.com, and FanSoft Media — with an eye toward the still-recent emergence of fantasy sports. (Unfortunately, it’s also yet another example of incorrectly crediting Daniel Okrent with inventing fantasy sports — even with the “modern” qualifier attached.)

– The FF Librarian has continued to crunch her Accuracy Challenge numbers and found Ask the Commish to be the top three-year performer in projecting fantasy tight ends.

– Fantazzle has launched a free-to-play fantasy game for the upcoming 2010 World Series of Poker, with the top prize a seat in the 2011 event.

A roundup of items recently posted on the FSB News page.

– The Fantasy Football Librarian has started to calculate and release “expert” accuracy rankings combining the three years that she has been measuring. So far, RotoWorld leads the pack for ranking receivers before the season over the past three years. Ask the Commish edged RotoWorld at quarterback.

– Dynasty formats in fantasy football seem to be gaining in popularity as both the overall pool of fantasy players and segment of serious players grow. NoOffseason.com is reaching out to that audience with its just-released Dynasty Draft Guide, published as an online magazine.

– Ready Set Go Fantasy Sports, the parent company of FantasyFootballStarters.com, has rolled out FantasyFootballHelp.com. The new site follows the still young trend of crowdsourcing by allowing users to create blogs, find articles and share advice and content with others.

– Yahoo! Sports blogger Kevin Kaduk (Big League Stew) identifies Silly Little Game as the weakest of the documentaries to date in ESPN’s “30 for 30″ series. We certainly weren’t fans either.
