Heads up, I would use Positional Splits instead of Primary Position to calculate team positional WAR! If you look at them side-by-side you can see where Primary Position gets wonky (I'd start with SS and LF as White Sox-relevant case studies).

Primary Position just sums up WAR by players' Fangraphs-listed primary position (leading to things like the Twins getting ~1300 PAs from their shortstops), whereas Positional Splits allows you to account for, say, Colson Montgomery being the backup 3B.
