Former Georgetown coach John Thompson Jr. has died, according to friends of the Thompson family.

Thompson was 78 years old, and there is no word on a cause of death yet.

Georgetown released a statement on Monday morning on behalf of the Thompson family:

“We are heartbroken to share the news of the passing of our father, John Thompson, Jr. Our father was an inspiration to many and devoted his life to developing young people not simply on, but most importantly, off the basketball court. He is revered as a historic shepherd of the sport, dedicated to the welfare of his community above all else. However, for us, his greatest legacy remains as a father, grandfather, uncle, and friend. More than a coach, he was our foundation. More than a legend, he was the voice in our ear everyday. We will miss him but are grounded in the assurance that we carry his faith and determination in us. We will cherish forever his strength, courage, wisdom and boldness, as well as his unfailing love. We know that he will be deeply missed by many and our family appreciates your condolences and prayers. But don’t worry about him, because as he always liked to say, ‘....”Big Ace’” is cool.”
