Just playing around, I decided to see how difficult it would be to generate 100 more players for the phantom "T207 extension set." Pretty easy, actually! Based on the 1912 rosters, all these guys played regularly or semi-regularly (100 IP or 150+ AB), yet are not in T207. They WOULD have been in the next group if the ATC had not been broken up
-- A lot of big names in there, even more than I thought--
