For the last few years, the MLB Division at FanSided has put together an offseason simulation with the sites playing General Manager. I am in charge of the Pittsburgh Pirates offseason simulation this year. Each team has been able to submit trades to one another as well as trying to bid on free agents.
Trade talks started early this offseason and the most interest was in Starling Marte. Marte represents an all-star caliber outfielder on a cheap two-year contract. There is an expectation that many teams will be checking in on Marte during the actual offseason so this makes sense.
