What a massive trade this would be as the Cubs would, in theory, land their ace in George Kirby, who is under team control until 2029.
Kirby was phenomenal in his sophomore season as he posted a 4.4 fWAR with 120 ERA+ in 31 starts for the Seattle Mariners. Given Kirby's trajectory, they would need to get a haul and this was a unique way to accomplish that.
For as much of a ceiling that Kirby has, including both Pete Crow-Armstrong and Kevin Alcantara likely would be a steep ask of the Cubs. One of the Cubs' two top outfield prospects would have to be included in this deal and it's likely that if Brown is the pitching prospect, the Cubs would need to add one more from the group of Jordan Wicks, Javier Assad, and Hayden Wesneski.
