The introduction to Major League Baseball begins through many sources.
We often to expect to hear about how a grizzly veteran put his arm around the young rookie and told him about the unwritten rules. We learn about the various tests young players will be given by experienced teammates to provide wisdom about how things are done. It is all part of the cycle of baseball life.
Yet we forget that lessons about how to adapt to life at the top will come from many more people than those on the roster with you. When you have close enough proximity to these players, and if they are humble and willing listeners, the information to help you adjust, can come from anyone.
