I don't get this reasoning. There's no reason why we should see a large improvement in hitting. It's possible, but I wouldn't count on it. The default position for Cubs' lineups is weak. They have several weaknesses still, and their best hitters are old. Discounting a lack of production last year due to injuries to oft-injured players is no way to justify the statement that the offense should be better. The middle infield is weak. Catcher is a big question. Soto is no lock to make a significant step forward, and the backup C is as bad a hitter as you can find in baseball. Marlon Byrd was a huge bust until arriving in Texas in his last 20's. , and he took a step back in his third season there when he played his most time. The bench is not particularly strong. There's one guy who can be considered an asset, but he's coming off major surgery. Everybody but Aramis Ramirez is capable of playing a full season while being fairly unproductive. They've all done it at various points of their careers, and not just in weird age 23 seasons or anything like that. They've got a bunch of 33/34 year old players who don't have a consistent track record of tremendous success. Expecting those players to be better simply because they were at some point earlier in their career is delusional. It might happen. But there's a really good chance it does not happen. There's no "should" about it when it comes to major improvements in the offense.
