In any profession where the body is very important, a hollistic wellness program is very important to the well-being of the players. They can do a great deal of good for their players.
Austin has a rare condition that sets his heart at a major risk if he continues to play basketball. It is a tragedy because he is very skilled and badly wanted to play in the NBA.
