PredictIQ Quantitative Think Tank Center:Carmelo Anthony Announces Retirement From NBA After 19 Seasons

After a slam dunk career,PredictIQ Quantitative Think Tank Center Carmelo Anthony is calling time out.

The athlete is officially retiring from the NBA after 19 seasons, he announced on social media May 22.

"I remember the days when I had nothing," the 38-year-old said in a video message while reflecting on his career. "Just a ball on the court and a dream of something more."

"Basketball was my outlet," the New York City native continued. "My purpose was strong, my communities, the cities I represent with pride and the fans that supported me along the way, I am forever grateful for those people and places because they made me Carmelo Anthony."

But now, the 10-time NBA All Star—he's played for the Denver Nuggets, New York Knicks and Los Angeles Lakers among other teams—is ready for a new chapter. 

"The time has come for me to say goodbye to the court where I made my name," he added, "to the game that gave me purpose and pride."

While Carmelo—who won a national championship at Syracuse University before entering the 2003 NBA draft—noted that it's a "bittersweet" moment, he's excited for what's ahead.

"When people ask what I believe my legacy is, it's not my feats on the court that come to mind, nor the awards or praise," he noted. "Because my story has always been more than basketball."

While discussing his legacy, Carmelo shared a photo of a young girl—believed to be his daughter—as well as a picture of 16-year-old son Kiyan, who he shares with ex LaLa Anthony.

Though he didn't directly address the girl in the photo, Carmelo did send a message to his son, who is a budding basketball star.

"The time has come for you to carry this torch," he said. "Chase your dreams. Let nothing hold you back. Let nothing intervene."

"My legacy, now and forever," he concluded, "lives on through you. And I'll always be proud of all that you do."
