All of our data sets are free to download and free to use. We have seasonal fantasy data going back to 1970 and weekly fantasy data going back to 1999.
We also have 2019 projection data from ESPN that can be used to compare actual points scored to projected points scored. The data was generated from league data of a 20 team league using the ESPN Fantasy Football API. Almost all players of significance are included in this data set, but beware there could be some data missing as it only includes those players which were rostered at least one week in that league. Again, given that it was a 20 team league, most players of significance are included.
