Developing fitness, skills is an NBA player's summer job

There is a well-known quote that permeates all basketball levels: "Players work on their individual games in the summer, and their team stuff in-season."

Thirty years ago, that was an accurate line, and perhaps in some high school communities it remains true today. But for NBA players, who routinely face constantly-changing schemes and major personnel changes, in-season development is more important than ever in remaining productive from November to June.
