His logic seems to be- If the youth take a step forward, and they have 5 decent starting pitchers, then the Twins should be competitive in 2017. They currently have 5 or fewer decent starters. They would be unable to replace Santana internally. They would be unable to replace Santana in free agency, or in trade, without overpaying. Here's where that logic is wrong IMO. In the offseason player valuations are determined by the free agent and trade markets. The same is true this time of year. But the trade market in July is overheated by the marginal value of 2nd half wins to teams in the playoff hunt. This doesn't impact trades in the offseason. It boils down to this IMO- sell now, while the trade market is hot, and rebalance later, when the trade market is cool.
