It was based upon the new rejuvenated farm system as well as Tex, Arod, Sabathia coming off the books and the slew of good players who are set to hit free agency in 2018. Harper, Machado, Kershaw, etc. I think the main piece was from a New York writer who just assumed emerging prospects, getting rid of deadweight and the Yankees being the Yankees shelling out 200+M on free agents. Fun to create the next dynasty on paper, but having it come to fruition is a different beast.
