Back of the napkin you'd probably say something like 83. Coming into the offseason they were at 74 https://blogs.fangraphs.com/the-absurdly-preliminary-2023-zips-projected-standings/ They've added this offseason 13ish WAR. That's not going to equate to 13 wins though because it was spread so much through the roster, rather than being concentrated in a few spots. So I think depending on how you evaluate some of the particulars you'd probably say they added 7-10 wins. I hate these analogies, but it's a high-floor, low-ceiling team. If things break well for the Cubs and they are in contention, they can use some of their vaunted depth in the minors to maybe get them to 90 or so wins.
