You are correct...apparently the booster club paid Bretz the funds mentioned with the description, "player development", and to my knowledge Bretz has never controlled any of the funds. It was stated that this has occurred since 2003.
It is sad, as my oldest played for Coach Bretz in the late 90's when we moved here, and I played recreational soccer with him. He is a great coach as well as a great developer of character in young men. Having said that, the KHSAA rules and evidence provided seem pretty clear on this. Coach Bretz also teaches, and I am not aware that he has lost his teaching job as well. I saw him at Keeneland last spring, and it was not clear that he would coach many more years anyway, even though he is not an old guy. Otherwise, he was bound for the hall of fame.
