There are seven Celtics alumni planning to play in the Tokyo Olympics.

By now you would have to be the most casual of Boston Celtics fans to just be learning that All-Star forward Jayson Tatum will be participating in the Tokyo Olympics at the end of July to try and help Team USA take home the Gold.
