Re: Trading "The Cuban Missile"
First, Chapman almost certainly will be an A type and would bring a draft pick with a qualifying offer so the Reds won't get nothing for him. Second, he is here for a couple more seasons after this one so it's not an immediate issue.
That said, if the Reds decided to trade him, the fact that he is relatively cheap, under control for a couple more seasons, and so very dominant most of the time gives him big, big value. A dominant closer has the most value to a true contender, though. That means he provides the Reds the most value as a Red, or in a deal to a team like the Tigers. Miami would be a poor target destination, imo.
