The problem is that all of the things that you listed that worked are associated with players who were already in the organization before this year. Even Green was already in the fold.
And once we start examining the things that went well from players already in the organization, it’s only fair to also note the stalled/backsliding development of Baty, Vientos, Alvarez, Mauricio, Clifford, Tong, Wenninger, etc.
