We're rolling on with the multi-year accuracy results - for those who are new to the blog, since 2007 I've gathered and analyzed preseason rankings from fantasy football experts and noted which expert is the most accurate with their rankings. You can see the results of 2009 here, 2008 here, and 2007 here. However, I think many of you would agree that an aggregate look at which site has been the most accurate across all three years is of even greater importance. So I posted the results for multi-year accuracy with QBs and WRs last week and tonight we've got TEs. For details on how the accuracy is calculated, just scope out one of the previous year's results, and to see the details on how/why I calculated a percentile average (remember: the lower the average, the better!) for the multi-year approach, take a look at the QBs post from last week. If you'd like a list of all 54 sites included in this analysis, scope out the WR post. Ten of those 54 sites have participated all 3 years, another 13 sites for 2 years, and the remaining 31 sites for just 1 year.
As with the QBs and WRs, I'm posting the top results for sites that have participated for different lengths of time separately since it's really not fair to compare those sites to one another. Sites should only be ranked relative to other sites that have participated for the same length of time, hence why you see below that I've broken it down into the best of sites that have been involved for all 3 years, top results for those who have only been in it for 2 years, and a few mentions for accurate sites with just 1 year of participation. Clearly I don't believe they can be compared directly but for some relative sense of accuracy, take a look at the percentile averages on the right side. Again, if your average is lower than your peers, that means you have performed with greater accuracy.
