I have a pretty similar situation to the original one on this thread, and i've been told that I should "wait until I see their development slow" to promote a top prospect. This makes some good sense, but I was just wondering what kind of a timeline I should look at in terms of seeing development slow. For example, Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Dean Diaz
improved in a couple of areas from Opening Day to the first Regular Season line, but didn't improve from the first Regular Season line to the second. Time to promote, or should I wait for another round of possible improvements?
