Everyone thinks the Cubs are down on Mervis. He's a good hitting prospect, nothing has changed. But you also don't bank on a position being filled by a rookie if you plan to contend. I highly doubt the Cubs would go into 2024 with Busch as their only good option at 1B either. Busch gets the shot at 1B over Mervis because he's the more advanced prospect so he gets first crack, it's not a reflection on Mervis, it's a reflection on Busch vis a vis Mervis. But Mervis is also there in case Busch struggles or is hurt. There's lots of things the Cubs can do with Busch and Mervis. Maybe Morel can't play 3B well and heads back to DH, Busch goes to 3B, and Mervis is the 1B. We don't know.
The Cubs like options and depth as they should. The Cubs really have no idea what Counsell is going to end up doing or what injuries will happen or who will perform vs struggle, they're just giving Counsell lots of solid options. We have no definitive idea who will end up at 3B, 1B, and DH and neither do the Cubs. Giving Busch a shot at 1B and using Morel/Madrigal at 3B and whomever at DH is a good starting point. Nobody last year thought Bellinger would end up at 1B and Tauchman our starting CF and Madrigal really good defensively at 3B.
