It depends on what you mean by "plan". Yes all teams trying to maximize the level of talent and depth they have in a system. No, there will never be a team who is 2-3 players deep in starting level talent on a roster. Between the limitations of a 26 and a 40 man roster, it is impossible to keep this depth of talent. Once you get past your starters you WILL see a significant fall off in talent. Once your back ups get hurt you WILL see another significant fall off in talent to your #3 depth guys. Yes, everyone wanted the Sox to add more players in this off season, but realize at one point the Sox started their #7, #8, and #9 OFs on their depth chart. Literally no organization in professional sports will have good player at that depth.
