Heat team President released a statement about the death of Dr. Jerry Buss.
Riley received his coaching start in Los Angeles.
Riley said: "Today, in the world of sports, we have lost a true giant. Jerry Buss was more than just an owner. he was one of the great innovators that any sports has ever encountered. He was a true visionary and it was obvious with the Lakers in the 80's that 'Showtime' was more than just Magic Johnson and Kareem Abdul-Jabbar."
Riley went on to credit Buss, "It was really the vision of a man who saw something that connected with a community. I was privileged to be part of that for 10 years and even more grateful for the friendship that has lasted all these many years. I have always come to realize that if it weren't for Dr. Buss, I wouldn't be where I am today. "
Riley credits Buss with helping to start his career, "I will always hold him and his memory in the highest of regards. Chris and I truly love Jerry Buss. He was a great friend and will be missed."
Dr. Jerry Buss was 80 years old.
