I've spent enough time around professional athletes to know the hardest thing for the all-time greats to do is say goodbye to the game they love. For some it's the loss of the locker room camaraderie, while others typically miss the adulation. A few have spoken openly about the money, though I'm sure for many more, that too is part of the equation, if only subconsciously. All speak of the shift in their identity. Imagine spending most of your life wanting to be something, achieving it and then having it ripped away forever through no fault of your own.
