I haven't thought deeply about this, but I think it's worth considering that there's a spectrum involved with the approach to the next 1-3 years. Yes, the last time the Cubs had a regime change they were very bad for several years in order to get the talent that propelled them to success. They also had a functionally barren farm system, no modern front office infrastructure, and were playing in a competitive environment with a reasonably tight correlation between spending and success. To compare, the Cubs have a new person in charge but a lot of front office continuity, a farm system that isn't at the top but is already further along in terms of supplying talent(especially depth), the new CBA and broader trends have loosened the correlation between spending and success, the modern game has rewarded roster depth more than it has in the past(though you still must have stars), and we've got pandemic league finances that make the current market a complete unknown in terms of the cost of players and their value in trade. They do have to make some opinionated decisions given the current roster, but they don't have to blow everything up if they aren't convinced the current group is going to be what gets them over the top.
