im guessing its just law of averages 500,000+ players and an increasing number of heart defects being discovered in athletes in America and some a few(Eddie Curry, Jason Collier(died in a similar manner as Antonio), Juwan Howard, and Ronnie Turiaf) this rash dictated many NBA and NFL teams to start manditory genetic testing for Hypertrophic Cardiomyopathy. i hope this will lead to big clubs in Europe doing the same.
