This article is inspired by this FanPost from BCB reader Theo’s Spare Soul, posted Wednesday. The theory was:
Who is a player from 1876 that had a long Cub career, and then pick a player who that person played with (at the end of their career) who then went on to have a long Cub career of their own (and so on and so forth until you get to the 2018 roster).
To avoid arguments later, let’s say that two linked players have to have been listed the same box score for at least one regular season game, and stretches of time as a Cub must be continual.
