Every one of the years you rebuilt, your farm was already good. This year is different. Also, every year of your rebuild saw a major drop-off in committed payroll, which wont be the case next year
Yes, the Yankees stayed mediocre and spent like maniacs. But their "rebuild" was in their handling of farm assets. You remember how the Yanks operated previously, right? Minor leaguer with a pulse, deal them off for now assets. Well, that changed when we got eliminated by Detroit. It took 4 years and a sell off to rebuild through mediocrity starting with bloated contracts and a poor farm system. It was augmented by spending and adding to the team. This is the current example that the sox will follow. They will try to stay relevant. They will still hand out contracts. They will eventually sell off. Their fastest return to glory using that route was shown by the Yanks at 4 years.
Our farm was already really good when we blew it up. The narrative that the rebuild was only due to dealing off assets is pure fiction. Judge, Andujar, Sanchez, Sevy, Montgomery were all in our system. The sell off allowed us to add Torres, Frazier and Sheffield (plus others) which allowed us to strengthen our position. But our farm was already really good when we sold off
