The Jays’ young position players are looking pretty good – even the ones who are not looking good. But the rotation (and to a lesser extent, the bullpen) is still a work in process. There are some promising young arms arriving in the second and third waves. but those arms are still a few years off, and even with Nate the Great possibly arriving in 2020 the Jays could use a little rotation help in the near-to-mid term.
That help could come via trade, but the prospect price would likely hurt.
