I only count WAR for the years that the players accumulated on their acquiring teams while under the team control at the time of the trade. In other words, I didn’t count any years added by new contracts or spent on other teams after subsequent trades. A positive or negative WAR is the result of the difference between the combined WAR for both sides as it pertains to Williams’s one.
