Each offseason SB Nation permits one volunteer to play general manager for each team, negotiating with the volunteers for the other teams.

Better deals have been found on this forum.
The award for the most lopsided trade goes to the volunteer general manager for the Seattle Mariners:
-- a trade of three Top 100 prospects -- Julio Rodriguez, Emerson Hancock and George Kirby -- for one year of Chicago Cubs third baseman/outfielder Kris Bryant.
Baseball Trade Values assigns median surplus values of $5.3 million for Bryant, $73.8 million for Rodriguez, $19.4 million for Hancock and $14.7 million for Kirby. In other words the proposed trade represented a combined $107.9 million for $5.3 million.
