I hesitate to put a lot of stock on the literal numbers for things like DRS or RAA after just 50 games, though it doesn't at least disagree with a crude number like defensive efficiency, which has the Cubs 12th. In either case, the difference between the Cubs current level and a Top 5 defense is just a few runs saved, and there's so much noise in that 50 game sample that I don't want to ascribe a ton of meaning to it. There's also the expected improvements from positive regression from the corner OFs and Mervis passing the eye test.
If there's one spot where defense has me concerned though, it's Morel. He hasn't looked up to the task of being a MLB OF so far this year, and that's really damaging to his potential role. Without being playable in the OF(and given how much Tauchman has played recently that seems to be the org's view at the moment), he essentially becomes a younger, more athletic Wisdom. That's a good thing to have, but a lot less helpful to the 2023(and 2024) Cubs that have Wisdom. Given that Morel's homer-fueled hot streak has dried up(2 for his last 22 w/ 10/1 K/BB), and Wisdom has stabilized a little bit from the deepest depths of his slump, I wonder if the best thing isn't Morel going back to Iowa to get as many OF reps as he can. I could even see the argument for getting him as many 3B reps as he can, with an eye on making him the best version of himself at his best position as the way forward. But the status quo doesn't seem sustainable there, and every day that Bellinger gets closer to returning or that Madrigal/Velazquez continue raking at AAA nudges us closer to that decision.
