Marfan syndrome diagnosis On June 22, 2014, Austin learned that he had been diagnosed with a mild case of
Marfan syndrome, a genetic disorder that affects the body's connective tissue, which caused NBA teams to reassess selecting him. In response, NBA commissioner
Adam Silver invited Austin to attend the draft as his guest. Shortly after Austin's diagnosis was made public, his agent revealed that Austin had taken out an insurance policy against career-ending disability through a special NCAA program, which was worth at least
$1 million. The policy would not have paid out if Austin's career ended due to his eyesight or his shoulder, but was expected to pay out due to his Marfan diagnosis. On June 26, 2014, between the 15th and 16th picks of the
2014 NBA draft, NBA Commissioner
Adam Silver made Austin a ceremonial pick, which fulfilled his dream of getting drafted. The crowd gave him a standing ovation as he walked up to the podium. He was offered a job in the NBA by Adam Silver, with the stipulation that he finish his degree at Baylor University.
