Novak Djokovic
Novak Djokovic is, by most metrics, the greatest male tennis player of all time. He has won more Grand Slam singles titles than any other man, and has held the world No. 1 ranking for a record number of weeks. This puts him in a rather exclusive club of athletes who have transcended their sport to become global icons.
His impressive resume does not, however, include anything remotely Jewish. Born and raised in Serbia, Djokovic is an adherent of the Serbian Orthodox Church, a fact he is quite open about. He is often seen making the sign of the cross during matches and has spoken about the importance of his faith.
While his career has certainly brought a great deal of kvell-worthiness to his family and nation, there's no hint of our kind of kvell. Unless, of course, you count the relentless pursuit of GOAT status as a universal Jewish trait. In which case, perhaps there's a sliver. But even then, we're reaching.
So, while we admire his talent and tenacity, we can definitively say that Novak Djokovic is not a Jew. We'll just have to kvell over his backhand from a secular distance.
