It's easiest to start with the things that we've learned, because it's a short list. We've learned that Rhys Hoskins is a hitter worthy of a spot in the top half of the lineup on any playoff contender. We've learned that Aaron Nola is a legitimate Game 1 or Game 2 starter in a playoff rotation. We've learned that Seranthony Dominguez has the stuff and the makeup to be a postseason closer. We've learned that players like Altherr and Zach Eflin and Andrew Knapp are, at best, depth pieces on a contending roster. And with that, we arrive at the end of the list.
