The downfall of the Chicago Cubs World Series winning core in 2016 was the fact that the team was unable to secure contract extensions with any of the star players from that team. Javier Baez was the closest member of the 2016 core to signing an extension as the team was believed to be in the final stages of a new deal in 2020 prior to operations shutting down due to the pandemic.
Baez was traded to the New York Mets at the Major League Baseball trade deadline in 2021 and that was the same deadline at which the Cubs moved first baseman Anthony Rizzo and third baseman Kris Bryant. The decisions that were made at the trade deadline led to a rebuild for the next season and a half and, to the Cubs' credit, the decision was the right move.
While the hardest part of the rebuild has yet to arrive, that part being the prospects reaching the Major League level and then finding success, there is no question that the team has established a pipeline of quality prospects that are expected to reach the Major League level over the next few seasons.
The arrival of prospects such as Pete Crow-Armstrong, Brennen Davis, Kevin Alcantara, and Hayden Wesneski will coincide with the Cubs' intention to return to contention at the Major League level. As the Cubs open their contention window back open again, there is one extension that the team should make soon and another extension that the team should avoid.
