Multi-year results for accuracy with RB rankings

Today we're going to take a look at the multi-year accuracy analysis for running backs. If you need a refresher on what exactly the multi-year analysis is all about, take a look back at my first post last week that looked at QBs. The primary thing to keep in mind here is that the number listed under average on the far right is the average percentile ranking for each site for their participation, and the lower the number, the better a site is at rankings as compared to their peers. Some of the 54 sites I looked at have been in it for 3 years, others only 2 or even 1. As with the other positions I've divided them up into the top sites based on length of participation.

Later this week I'll be posting the results for top overall accuracy across all 4 positions, so stay tuned for that. One thing I'd like to point out here is the best average percentile difference between the positions. I'm looking primarily at those sites who have been in it for 3 years since they have the most data we can go on here...you can take this all in yourselves but just a quick snapshot to show you what I mean - the best site for QBs (Ask the Commish) had a 30th percentile average; for WRs (Rotoworld) it was a 29th percentile average; TEs (Ask the Commish again), another 29th percentile average...but here with the RBs (another Rotoworld victory) it's significantly higher at a 38th percentile average. Interesting. Anyway, without further ado...


Sites with 3 years of participation:
Ranking Site Average
1 Rotoworld 0.38
2 Sports Illustrated 0.43
3 Yahoo! 0.48
3 ESPN 0.48
5 FFToolbox 0.50



Sites with 2 years of participation:
Ranking Site Average
1 KFFL 0.05
2 Fantazzle 0.26
3 Pigskin Addiction 0.28
4 FFToday 0.32
5 Fantasy Hulks 0.33



Sites with 1 year of participation:
Ranking Site Average
1 Draft Analyzer Ultimate 0.02
2 Numbers & Guts 0.04
3 Accuscore 0.10

Keep up the good work. It's nice to see how these "experts" actually faired in relation to one another.

A hiatus

Update:  It is with a very heavy heart that I tell you all that yesterday, August 30th, I delivered our stillborn daughter, Caroline Mary. This has been an almost surreal and definitely heartbreaking experience and I appreciate the support in each and every one of your notes. Caroline will be honored and loved always. Thank you, thank you, thank you for your thoughts and prayers - they mean the world to our family. I have been a very poor blogger this month and feel I owe you all an explanation, particularly as this is crunch time for draft prep. I hope this is not too personal of a look into my life since I know most of you are just here for the football. I am nearly 18 weeks pregnant and we have learned that our baby (a little girl!) has triploidy, a chromosomal abnormality that means she has three copies of every chromosome instead of the normal two. The doctors have explained that it's a completely random occurrence and fairly rare that she has made it this far along, but tha...

Labor Day FF links

Happy long weekend! Here's hoping most of you are free to enjoy the 3-day weekend and the relaxation and fun that comes with it. I spent my Sunday participating in 3 fantasy football drafts scattered throughout the day and night, but I think I've finally wrapped up my drafts for the year. So like many of you I'm now turning my attention to the Week 1 games! But before we get to some player rankings and prep for Week 1, I want to make sure that all you experts out there are aware of the upcoming deadline for the annual accuracy contest that I run with the Fantasy Sports Trade Association. I compare preseason positional rankings from experts to the final outcome of the fantasy season to see which site had the most accurate preseason rankings, and this year's deadline is fast approaching: September 9th by kickoff. Check out the info on the FSTA site for more details and be sure to e-mail me your submissions. Now, onto Week 1! First up, let's get to some of this...

2014 Average Position Rankings spreadsheet

Friends, I've got a first draft of the 2014 Average Position Rankings spreadsheet up here as a google doc. If you're new to this annual spreadsheet or need a refresher, here's the scoop. I take the top 200 or so overall rankings that are freely offered by a handful of sites and I average out their rankings for each player. I also take the standard deviation to see how a player's rankings differ among experts, and add that in as another component to give you a sense of how much consensus there is on a player. I drew from the following sites this year: FFToolbox, CBSSports.com (both Jamey and Dave), ESPN, FFCalc's ADP, The Fake Football, The Football Girl, NFL.com, DavidGonos.com, SI, Yahoo, FantasyPros.com, and RealTime Fantasy Sports. All offered roughly a top 200 overall ranking and you can see each site's ranking (gathered 8/20/14) in the second tab on the spreadsheet. You'll see that I really haven't fleshed it out a ton yet - I still have to ge...
