Historical team OPS Differentials

I did some copying and pasting and searching in the Baseball Reference Play Index and made a file of all team OPS differentials from 1908-2018 (I had to enter OPS allowed for NL teams 1921-22 using data from Retrosheet). Some of the numbers are a bit different than what I have at some of my past blog posts. The 1927 Yankees are now .201 (no longer just .196), for example and the 1913 A's are now 2nd, not the 1939 Yankees. Baseball Reference does not have the 1906 Cubs  OPS allowed but Retrosheet does and has them with a .131 differential (.667 - .536). The Astros this year are at .182 so far (.834 - .652). This is an Excel file
