I had the privilege of serving as the Colorado Rockies general manager on the 2019 SB Nation Offseason Simulation. I can conclude that I lost several years off my life trying to make the perfect deals for my favorite ball club.
There were several deals made, several close to being made, and several not considered whatsoever. This whole event took place over a 48-hour period from 3 PM MT on Sunday, November 3, until 3 PM MT on Tuesday, November 5. The nice thing about this simulation is that it rewound to the end of the regular season.
