Most accurate fantasy football experts, 2008-2011

Greetings. As longtime readers are well aware, since 2007 I've been running a contest that analyzes the accuracy of fantasy football experts' preseason rankings. I look at rankings for each of the offensive skill positions and generate results for each position as well as an overall accuracy winner across all four positions. You can find the details behind how the annual rankings are created here with the 2011 results as posted to the NY Times' Fifth Down blog back in January.

If you're uninterested in the details of the contest and just want the results, skip ahead through the next few paragraphs to the charts below. Otherwise, read on.

We all know that accuracy results from one single year are great, but obviously when you combine several years you get a better picture of which sites really excel. I ended up throwing out the 2007 results I had since I ran that contest by merely looking at sites' overall rankings; in future years I switched to looking at specific positional rankings. Over the course of the contest from 2008-2011, I have amassed submissions from 79 different sites/experts. I decided that it's really not fair to combine the sites that have participated for just 1 year with those that have been in it for multiple years; too much can happen in 1 year, good or bad. So I threw out all sites that only participated once, which amounted to eliminating 33 sites (note: this includes Fantasy Shrink, the 2011 winner, though it also includes a few sites that aren't even in business any longer).  For those that are curious, 17 sites have participated for 2 years, 12 sites have participated for 3 years, and 16 sites have participated all 4 years.

In creating the original rankings I developed both a score (essentially the accumulation of points from all players in a position by measuring the difference between the expert's preseason ranking for a player and the actual ranking of that player at the end of the fantasy season) and a ranking (based on the score relative to other participants) within position. Now in order to get at the multi-year results, because the scales differ from year to year, I normalized the scores for each year where 0 is the average expert, negative scores are more accurate than the average expert, and positive scores are less accurate than the average expert. I then averaged across the number of years that that expert had participated. I thought about creating the multi-year results by merely averaging the rankings but decided that the scores are a more appropriate way of analyzing sites since it rewards the more accurate sites and punishes those who were just way, way off.

What you have below is a list of only the top sites that have participated at least twice. Each year when I ask for participants in this contest I promise that only a top percentage will be displayed to the public. I do this largely to keep sites participating but also because I'm really not in the business of spreading bad news about sites. I completely understand your desire to see the full list but hope this abbreviated version will do.

Again remember that due to the normalization I did, negative scores indicate more accurate predictions relative to the average expert. So here, negative = good.

First up, the overall accuracy across all 4 positions from 2008-2011:

Next, quarterback accuracy from 2008-2011:


Running back accuracy from 2008-2011:


Wide Receiver accuracy from 2008-2011:

Finally, Tight End accuracy from 2008-2011:

Congrats to the crew of fantasy writers/rankers at!

Can we get a list of the 46 experts who were analyzed? I like seeing teh winner, but also want to see if, for example, Andy Behrens was eligible?

For some reason, I cannot see anything in the rankings boxes. Can you advise or change it so its just a list and not an apparent image?

When you say Pro Football Weekly Fantasy is that Pat Fitzmaurice in particular or consensus? Same for FootballGuys, is that David Dodds or another individual or their consensus rankings? Putting in paranthensis who at each site (like you did with Dave Richard) would be very helpful. Thanks for all your hard work on this.

I can't see anything on the boxes either. If I click on them, they open a window with nothing in it.

I just want to thank you for this!
I'm sure it was a lot of work compiling and working with all this raw data. I just wanted to let you know how much I appreciate your work!
Cheers and good season!

Back on the fantasy wagon

With my library conferences behind me (for a few weeks at least), I can now concentrate on fantasy football again. If you happen to be a librarian and are interested in how my co-presenter and I tied together fantasy football and information literacy, check out my co-presenter’s blog . Though I imagine most of you would much rather catch up on the following football news and thoughts for the week: I remain a bit dazed and confused by my certainty last summer that Cedric Benson was going to rock my RB2 world in 2007. Didn’t happen and now he’s moved onto ankle surgery, alleged intoxication and resisting arrest on boats. Awesome. You can practically taste Matt Forte’s value skyrocketing here. In fact, wondering about rookie RBs in general? Well then check out FF Xtreme’s The Day After: Ranking the Rookie Running Backs . I love reading articles or stats that challenge my preconceived notions – The Fifth Down’s Chad the Completion Percentage Machine does just that. No offense to thos

Streaming Defenses - Week 16

Don't know about you all, but in our house this week is just chock full of events, visiting with family, and getting organized for our upcoming time off over the holidays. Lots of scrambling going on around here and attempts to install some sense of gratitude in my boys. What am I grateful for this season? Many things but let's start with Bob. Bob has been my fantasy football rock, coming back week after week to post. Hats off to you, Bob, and thank you for your diligent work and research. So here he is with this year's final streaming defense post.  Well it’s the last week of the Fantasy Football Playoffs in most leagues, and my last post of the season. I hope you all found these posts useful. And if I failed you, you have to murder a lot more experts before you get to me. I myself have had a terrible playoff season. I’m out of all but one of my leagues due to the weird games the last two weeks. Between weather that didn’t materialize to normally consistent players co

Start/Sit Week 4 and a smattering of rankings

It's been awhile, my fantasy football friends. I have lofty intentions of getting several posts up here each week, but life is busy and I will do my best. So in the intervening 6 years since I've posted regularly on here, our family added another child (now there are 3!), moved back to Boulder for a sabbatical year and then returned to Knoxville, and we have basically been chugging along like many of the rest of you. My two boys (who turn 12 and 9 soon) are in a fantasy football league for the first time this year with their buddies, which ostensibly is the just the dads (and mom!) playing one another of course. But my oldest is taking it super seriously and what kind of Fantasy Football Librarian would I be if I didn't step up my game for him? So I'm back - and am interested in the fantasy landscape - lots of the same awesome sites out there, but many new ones as well. I'll try to incorporate a mix. Please be sure to let me know if my 2006 ways aren't working i
