So let's say you cash prospects at the deadline in an effort to make the playoffs. And you end up missing the playoffs. Where does that leave you; a barren farm, a year older Springer, a year closer to Vlad and Bo free agency, etc.
As I said, this does not look like the year to move prospects to fill holes. If the Jays unexpectedly win 3/4 of their games between now and the AS break, the calculus might be different.
