Read each row as: J.J. McCarthy, plus anything in “went with”, was traded for what is in “came back”. Margin is the value gap at that day's prices from the side that received J.J. McCarthy; positive means that side came out ahead.
Players J.J. McCarthy has most often been on the opposite side of a deal from. Each page holds those deals: how many were straight one-for-ones, and which side kept having to attach something to close it.
