The WAR number is a combination of B-Ref and Davenport, the best WAR that exists for historical comparison. Additional numbers are OPS+, plate appearances, WAR/Plate appearance, and the number of Most Valuable Player Quality Seasons (8 WAR seasons - 8 WAR is an MVPQ, 10 WAR is an EMVPQ, 12 WAR an EEMVPQ, 14 WAR an EEEMVPQ)
I've got each position carried out to 32 slots for a project that I don't believe fits this space, so I'll just include the top 25 here. I'll also include last player out. For some players, it's hard to slot them at a particular position (where does King Kelly go, for example) so I just chose one (if you don't see a first baseman in the top 25 who you know should be there, maybe he's a third baseman instead).
Each player is only listed with one team - the team that is most representative of his MLB performance. This is just merit, that's the only way I rank stuff - it's not social impact or the quality of their character. It's performance.
