It takes more like 5-6 seasons to build the pipeline to have prospects knocking on the door as arbitration time arrives. Using the rule 5 draft to build ML and organization depth while you build, find what is undervalued (defense, starting pitching, low contact power, etc) and capitalize on it, have a plan for your priorities, and make sure you don't pick someone in the early rounds of the draft who doesn't pan out. In the playoffs, you need 5 stud pitchers to carry you (your 3 starters and two top relievers), with your starting 8 all above average with a couple of studs. Once in the playoffs, if you have maximized your chances, that is all you can do. Correct me if I am wrong.
