A Look at Yahoo and ESPN Owned Percentages

by
April 24, 2010

I have had several discussion in the comment here at Fangraphs that the players we discuss are not available in the reader’s leagues. I decided to look at the percentages owned at ESPN and Yahoo and see how they compare. Also I will look at what size of league in total players on rosters corresponds to what percentage owned.

I have seen some huge discrepancies in the owned percent between Yahoo and ESPN. I took the percentages of the top 250 owned pitchers and hitters. I didn’t match them up, I was more looking at just the percentages. What I found was that there were basically 3 zones of players. Those owned by all teams (>90%), those owned by some teams (more than 10% and less than 90%), and those owned by few teams (<10%). Of the 500 total players 194 were in the top 90% for ESPN and the top 114 for Yahoo. In next bracket of players, ESPN has 107 in that group and Yahoo has 245. ESPN leagues seem to take more top players and then drop off quickly, while more of the middle players are used in Yahoo. This leads to be believe that Yahoo has larger leagues as a rule and the percentage owned will be higher.

The following data is the percent owned for the different sized leagues. The number is for the total number of players (roster size * number of teams).

Total Players Yahoo ESPN
200 – 66% 87.8%
250 – 45% 58.4%
300 – 26% 11.5%
350 – 11% 3.7%
400 – 6% 1.7%
450 – 3% 0.5%
500 – 1% 0.2%

With these numbers and taking into account previous comments, I will write only on percent owned cutoffs for leagues of 300 total players or higher.
