I hope you brought your big monitor to work today because you're going to need it. After looking yesterday at the longest running current trade chain for the Reds (it's in the fanshots, so you probably haven't seen it), I decided to take a stab at mapping how and when every player on the 40-man roster joined the organization. My starting point with each player is the first person in their chain who was either drafted or signed by the Reds and then I went from there. Hopefully it is self-explanatory.
